Description

DEVICES, APPARATUS AND PROCEDURES FOR DISSEMINATION, BILLING, PAYMENT AND REPRODUCTION OF CONTENTS OF DIGITAL MEDIA DESCRIPTION The invention relates to devices, devices and procedures for the dissemination, billing and payment of digital media contents. The Internet, as a global digital network, serves excellently as a technical platform for the distribution of digital data from content providers to its customers. Media content such as texts, audio content such as music or language, images or mobile video content are produced almost exclusively in digital form today or can be digitized with little effort. Thanks to highly developed compression techniques, such as MP3 (for the audio field) or MPEG (for the video field), it is also possible to transport data-intensive contents through the Internet infrastructure, still in use today. relatively narrow on the consumer side. Also the programming elements for the use by the buyers are included among the aforementioned digital contents, in the context of the present invention. Typically, a provider of multimedia content of that nature operates a particularly powerful computer, called a server, which is permanently connected to the Internet through a dedicated broadband. Customers of content providers must respectively have access to a connected or connected computer to the Internet, for example, what is called a personal computer (OC), and using convenient Internet service protocols, such as, in the case simpler, for example, the "hypertext transport protocol" (HTTP) download the data representing the content of the server on the local computer (client). In this context, digital content is initially stored frequently in the form of a file on the local computer before it can be used there. As an alternative, what are called real-time transport protocols are offered, where the data representing the content is converted directly to sensory-perceptible impressions during the download of the server's computer to the client's computer without generating and storing a file that corresponds to the digital content on the client's computer. For a long time not only fixed equipment in the form of a connected PC or that can connect to the Internet through transmission routes by lines have been considered as client computers. Mobile equipment is available that can be easily carried by a person. Examples of this are compact playback devices ("players"), for example for MP3 audio files or digital reading materials ("e-books"). Recently, equipment for converting digital content into perceptible sensory impressions having a wireless radio frequency connection to the Internet has also been known, for example, via mobile telephone networks such as GSM or UMTS. Usually, different types of media are distinguished with respect to the technical devices and methods used to convert a digital content to a form that can be sensed by a sensorial means by a consumer. In the case of texts and images, including video sequences, the sense of sight is stimulated and the terms "display device" and "deployment methods" are used. In the case of audio media that stimulate the auditory sense, the terms "reproduction devices" and "reproduction methods" are used. Digital media can also stimulate other senses, in particular the sense of touch and the sense of smell. The object of this invention relates, in its most general form, to the conversion of all these different types of media to a form that is suitable in a specific situation for perception through the senses. The inventive aspects in general that are explained in the subsequent text, apply, notwithstanding specific expressions such as "screen", "reproduction", "reproducing", etc., basically to all forms of media consumption while not being explicitly limited to specific types of media, such as page - oriented to a text element, for example. The use of programming elements is also included in this, and since, even when the programming elements are in operation, for example a computer game or a program for the processing of a text element, the consumer interacts at the level of sensory perception. Notwithstanding the foregoing, it seems inevitable that specific examples that are introduced for illustrative purposes are restricted to specific types of media. There are unresolved problems regarding billing and payment concepts for this type of modern digital content distribution. Experience has shown that the first and fundamental question is whether a customer is willing to pay - to the respective content provider for the consumption of digital content via the Internet beyond the cost involved in the Internet connection itself. The answer to this question depends essentially on the necessary technical infrastructure. · For example, a company (MP3.COM) that is based in the United States offers a service including the provision of all Internet users with the possibility of downloading free of charge content in the form of audio files in MP3 format, that could originally be purchased only as CDs (compact discs) of audio. The original concept originally included a control component with the feature that the download of the MP3 audio file associated with a specific audio CD from a central server operated by the company had been made available to an individual customer only if this customer had transmitted previously a data sample characteristic of an audio CD corresponding to the server, in order to verify that the respective client had already purchased a copy of that CD and that the supply of the corresponding MP3 audio file was covered by restrictive clauses of the law of copyright. This method can not be considered promising for the future, for several reasons: 1. On the one hand, at least as far as the United States is concerned, it has become clear since then as a result of legal procedures, that at least The original business model may not be covered by the qualifying clauses of the US copyright law. UU On the other hand, in accordance with the theory of the business model, the flow of money from the consumer to the supplier is still based on the sale of material goods, since the client must have the possibility of accessing the server only through the purchase of the corresponding audio CD. This should be considered a disadvantage in the age of the digital economy of the Internet. As a result of the fact that MP3 audio files that are downloaded from the server represent, in extremely good quality, the goods that were originally marketed on the audio CD, and also can continue to be distributed through the Internet, largely without cost and without further ado. loss of quality, there is an incentive for the customers of the company to offer on their side the MP3 audio files downloaded, free of charge, not only to close friends or relatives, but to the general public. As a result, the service provider loses its revenue by distributing the MP3 audio files to a much wider audience than the original buyers of the audio CDs. 4. Finally, the temporary possession of a suitable audio CD is not equivalent to the legitimate possession of a data carrier, that is, it is not possible to exclude situations where audio CDs are provided for a short time by an owner to other parties. with the sole purpose of obtaining access to the server. Possibly also in view of the defects of the billing concept of MP3.COM previously described, another company, Napster Inc., based in the United States, developed another business model, where its users get free of charge access to, particularly, content. digital present as MP3 audio files. In this concept (sharing files in shared networks) there is no longer a central server to archive digital content; MP3 audio files and other content are stored exclusively on customers' local computers under the control of the company's customers. Napster's central server only offers the function of an intermediary, that is, it receives requests from Napster clients for a specific digital content and then supplies the Internet address of clients' computers from which the corresponding file can be extracted and downloaded. In accordance with that system, it is only possible to extract what at least one Napster client keeps ready for access and download at a given moment in a computer under its control. The original business is based on the idea that a non-commercial exchange of elements protected by copyright between private individuals is covered by the limiting clauses of the copyright law, and it is assumed that the commercial activity of intermediation by Napster does not violates the private and non-commercial nature of the distribution of digital content. In this case too, it seems to have become clear that the business model can not at least comply with the restrictive clauses of the copyright law of the US. üü In the known concepts of shared networks there are no provisions under the concept for a cash flow from the consumer to the content provider. The owners of the copyright of the digital content, therefore, experienced a significant deficiency in technical concepts available in order to be able to charge and collect adequate payments even in the conditions of the Internet economy. In this context, technical methods, basically to inhibit the transactions of shared networks, for example at the infrastructure level of the access providers to -Internet through mandatory filtering of the flow of data on the Internet, seem to be loaded with problems.

On the one hand, for political and legal reasons it is doubtful that these concepts could be implemented at the scale with the necessary amplitude. On the other hand, new technical contexts are continuously being developed to protect the exchange of files through shared network transactions, including, not least, against legal or administrative intervention. An example for this is the protocol of file transfer over shared networks "Gnutella" which, contrary to the concept of Napster, does not require a central server as an intermediary. The ability to identify subscribing clients for a protocol of that nature and the related possibility of taking action against the use of these technologies at a legal or administrative level are now being undermined by cryptographic anonymity techniques, such as those included in called the "freenet" protocol. Adequate protection against unauthorized reproduction is a condition of basic technology for the possibility of sustained billing for a payment for the use of digital content by consumers. If this problem is not solved, an economically viable invoicing does not seem possible. Cryptographic concepts offered for these purposes are those, in which - files comprising digital content are distributed both by Internet and by physical data carriers such as CDs, exclusively in deciphered form, and / or in which files comprising digital content are offered with hidden information by steganography, known as "marks of water ", which provide information on the situation regarding copyright of the element contained in the aforementioned files and that can not be deleted from the file representing the digital content by the consumer with non-legitimate technical manipulation. As a result of this method, the cryptographic keys needed to decrypt the files have been effectively and reliably protected against any unauthorized access by third parties, in particular also against access by consumers. This can be conveniently implemented by the content providers offering in the market, or allowing other interested companies to offer in the market, special equipment, in whose functional trustworthiness the service provider trusts and in which, particularly, cryptographic keys are included, preferably , for example, in specially sealed sub-assemblies, in which convenient technical measures ensure that the stored cryptographic key is instantly erased as soon as an attempted tampering is detected. The embedding of watermarks in digital content alone does not yet offer a consistent basis for a practical way of billing for use by media consumers. This also requires, on the part of the service provider, to control the level of equipment by which consumers make use of the digital content. In this context, the team, in whose functional trustworthiness the provider or service providers rely, is built in such a way that the aforementioned team removes the embedded copyright information by filtration by steganography and evaluates it in a convenient manner in order to to effectively inhibit unauthorized use processes, in particular, unauthorized reproduction. An example of such a technical infrastructure is known as the SDMI project (Secure Digital Music Initiative), in general, devices and methods that have the purpose of technically implementing the monopoly position, in accordance with the law of Copyright, the copyright holder or his legal successor to the digital content, are called "Digital Rights Management Systems - DRMS." Technical concepts for DRMS are known, for example, from the US. -A-6, 112, 181, and also from US-A-6, 138, 119. However, such closed technical infrastructures with a DRMS that inhibits the consumer on an effective and consistent basis of making any use of digital content that has not been authorized by the content provider, it still does not solve the problem of allowing, as much as possible, a flexible distribution, billing and a digital content payment both through the Internet as through data carriers such as CDs. However, in an inventive method for the distribution, billing and payment of digital media content, as in a corresponding device offering a connection to a DRMS that is cryptographically protected against misuse, it represents only a preferred form of implementation.; similar cryptographically protected DRMS is not absolutely indispensable. DMRS are known that can be added to the digital content with charge concept information through convenient technical concepts. For example, the XrML (Extensible rights Markup Language), based on XML (Extensible Markup Language), whose specification is available at http://www.xmrl.org/, contains measures to configure charging concepts information in a convenient way for data processing systems. However, these methods still do not satisfactorily solve the problems that arise in the area of technical realization of billing and payment processing. As things stand, closed systems, including DMS, will gain market acceptance only if they offer the consumer also perceptible advantages, since the presence of the DRMS first tends to be seen as an obstacle by the consumer. However, it is also not true at all that consumers will not be willing to pay charges to the content provider for the use of digital content; what is important, rather, is the fact that the modalities of the billing and payment processes do not correspond to the wishes of the customers. In regard to this, there are considerable deficiencies in the current state of the art. One of the problems of state-of-the-art systems for distributing, billing and paying for digital content has been that they are based on concepts of a charge-for-purchase scheme or a subscription charge scheme that are too inflexible. For example, systems are known where, for example by means of payments with credit cards, it is necessary to pay a full purchase price, before a file constituting a digital content can be downloaded from a server. This leads in particular to a situation in which the review previously free of charge of the digital content by the consumer to determine whether it is appropriate, is to his liking, etc., is no longer possible. This represents a considerable obstacle to the acquisition of digital content through purchase, since if the customer is not satisfied, it is generally impossible to invest the purchase since, contrary, for example, to the purchase of a book or a CD physically, it is very difficult to reliably rescue from the client the right of relevant provision on the file that has been delivered in the form of a copy. On the other hand, there are known systems that allow the distribution, billing and payment of digital content depending on the use, using the "video on demand" method. However, such systems have the disadvantage that the detailed characteristics of billing processing are related to the presence of a data connection between the terminal (client) and a server of the content provider. Even though the costs of data transmission using modern telecommunication equipment are continually being reduced, it is currently unrealistic to assume that consumers will always have uninterrupted and secure access to telecommunication networks at low cost when they are using digital content. . An important social aspect regarding the use of media is the consumer's option to be able to act anonymously when acquiring means, for example, buying physical means against cash payment in a position. The known digital concepts of distribution, billing and payment using data exchange networks such as the Internet in particular are based on the possibility of identifying the individual consumer. There is a requirement for a technically improved infrastructure for the distribution, billing and payment of digital content, where the consumer can also act anonymously. It is known that both the market for digital content and the market for technical equipment with which digital content can be presented to the consumer in the form of sensory perceptions, are characterized by a level of competence that has generated a great variety of technical achievements of this technical infrastructure. However, for the customer it is a significant disadvantage if that diversity also generates a large number of billing and payment systems. In practice, the result of this diversity is that the consumer is expected to enter a large number of individual contracts with supplier payment systems, for example, credit card companies, companies for payment systems based on mobile radios, and others. The level of acceptance of technical infrastructures for the controlled distribution, billing and payment of digital content is noticeably reduced due to these disadvantages. The object of the invention is, therefore, to specify a device and a method for the distribution, billing and payment of digital content, where the aforementioned disadvantages are reduced or overcome and where, particularly, a billing process is possible very detailed without a permanent data connection, for example, with a billing server. The objective is achieved in accordance with the invention by the features of the independent claims. Advantageous refinements of the invention are included in the dependent claims which refer to the respective mentioned claims. The inventive solution offers an improved technical infrastructure for the distribution, billing and payment of digital content, - being that the mentioned infrastructure allows the implementation of a partial or total deviation of the rigid connection between the use of media and the purchase of material carriers. of data such as CDs, DVDs or video cassettes. In accordance with the principle of conventional media use, the consumer acquires, through a purchase transaction, an individual copy of a physical data carrier with the content recorded in it, and may use the aforementioned copy to his own taste: On the one hand, this method leads to a situation in which the full purchase price is charged even when the consumer uses only a part of the content stored in the data carrier. additionally, the distribution of the content, of means through sale and commercialization of physical copies requires a complex and expensive logistics for the manufacture, storage and distribution of the data carriers. However, on the other hand, the physical characteristics of the data carriers allow the invoicing of the charges that must be paid by the consumer being handled in a simple way in comparison, provided that the uncontrolled copying of the data carriers is sufficiently unattractive for the consumer, for example, in view of the effort required to make copies or in view of the unavoidable detriment of quality levels, as inevitably occurs when making analogue copies of audio or video cassette content. However, the high transaction costs due to the physical nature of the data carriers are automatically eliminated when switching to the non-physical distribution of digital content through data networks, at the same time any possibility of distinguishing between the "original" is lost "of a file representing the digital content that has been legally acquired through a purchase transaction, and copies, which were manufactured virtually without effort or without incurring costs. When files are distributed digitally over data exchange networks, particularly the Internet, the difference between "original" and "copy" no longer makes sense at all. The solution according to the invention is therefore based on the idea that in a digital economy the purchase of, copies of a file representing a digital content, with the right of subsequent use of the consumer who acquires the copy, right which is the logical consequence of the purchase, must be replaced or at least supplementary by the concept of allowing (usually against payment) access and use rights ("access rights") to the consumer, who, however, as a result of that will no longer be in a position to exercise the corresponding right, typical of their possession, to dispose over a data carrier. As a result of this paradigm shift, moving away from purchase and ownership and towards the temporary granting of rights of access and use, - on the one hand, there is a solution to the problem that files representing digital content can be copied at will, since the A properly configured technical structure means that the possession of ["original"] files by the consumer is no longer decisive for the process of use; while in fact in the context of the inventive solution the archives as such can be copied and distributed at will by the consumer without affecting the interests of the owner of the rights negatively, in accordance with the inventive solution; only the critical information of access right, which is necessary to use the content of the files, now in turn, must be kept strictly under control through technical means; on the other hand, the risk that derives from the dependence of the consumer on the permanence of the concession of the rights of access and the rights of use by the service provider becomes potentially greater, because the model of access and use is based on the assumption that the consumer can continue to have access to a service provider who is willing, prepared and also able to provide the service to which the consumer is entitled based on the rights of access and use. If the service provider, for whatever reason, terminates his business or discontinues the marketing of a specific content, for example, for economic reasons or in response to external pressures, the consumer will no longer be in a position to have access to his copy acquired that would have taken possession and filed for consumption and permanent use, something that would have been possible with the model of purchase and possession. The; The solution according to the invention thus offers, in particular, a technical infrastructure by means of which a concept of access and use is technically possible as a substitute for or complement to the purchase and possession model: The aspect of integrating a module of card to a solution according to the invention, as explained in more detail below, also makes it possible to synthesize "use" and "possession", since the right of use can be linked to a physical object that is difficult to duplicate and it also incorporates for the consumer in a perceptible way the rights of use that are being transferred to it. Thanks to the advantages of the inventive solution it is possible to return the concepts involving charges for the use of digital concepts more attractive to the client in comparison with the resources to exchange files free of charge, since it is offered to the consumer with more than just a a file incorporating digital content: on the one hand, a uniform quality standard is ensured, that is, contrary to the non-commercial file exchange resources free of charge, the consumer does not have to consider files arranged in a technically inadequate way, and thanks The concept - explained in more detail below - of the status rights and their technical implementation is possible, at a commercial level that offers the consumer attractive additional features, in addition to and beyond the file that represents the technical content. Portal technical solution A first aspect in combination with the invention is that the distribution, billing and payment of digital media content can be performed for a large number of content providers and for a large number of consumers by means of a technical device for processing portal data. In particular, wide-area networks (WANs) can be used by both content providers to upload files consisting of digital content to the portal data processing device, and also by consumers to download the aforementioned files. portal data processing device. Here, in particular, two executions are offered: selective individual transmission of specific content "on demand" of the portal data processing device that is operated on the consumer side, and - non-targeted transmission of specific content with "broadcasting" techniques "-, from the portal data processing device to a non-specific number of devices operated by a set of consumers. The portal data processing device can also manage access and use rights and collect billing data from devices that are operated by consumers, and based on this billing information can perform the billing of both the usage charges that must be paid by individual consumers, and the billing of royalties that must be paid to individual content providers. Finally, the portal data processing device can also perform the corresponding payment processing. It is particularly advantageous if the portal data processing device is operated in a mode where the content of a large number of right owners is marketed jointly: - on the one hand, the consumer is spared the need to hold an amount of individual contracts with the owners of the rights; all that is required is a single global contract with the portal operator. - On the other hand, the portal data processing system can be configured as content storage for all files with digital content that have ever been commercialized, which places the portal operator, in front of the consumer, in the position to adopt the type of "guarantee position" with respect to the future availability of service that is associated with the right of access and use. Even if the owner of the right has discarded a certain content and no longer wants to continue with the administration and maintenance of the respective files (called "Abandonware"), the consumer can receive the service according to their rights of access and use through the portal data processing device. The portal data processing device can also be configured so that it can operate as a file sharing component of shared networks. In a context of this nature, files consisting of digital content are kept available for selection, for example, in customers' computers that are operated by consumers. The administration of access and use rights and functions related to billing and payment typically remain in the portal data processing device in that case. Off-line mode A second aspect of the invention consists in the fact that the billing and / or payment of charges that are due to the use of digital content, does not necessarily have to be configured in synchrony with the process of use itself . That is, depending on the credit policy of the content provider or the billing companies, the consumer can be allowed to use the digital content to a certain degree by a convenient inventive device, without the need for a flow connection of permanent data, in particular to the portal data processing device, during that period. For that purpose, during a time interval between two billing periods, all the necessary data relating to consumer use behavior are accumulated locally for use in the next billing period as a basis for billing the charge due for the use according to the contract. These registered data are ensured, preferably, by the use of suitable technologies, against unauthorized manipulations, in particular by the consumer. It is possible to ensure that the consumer has to make a deposit to cover the credit risks as a result of the digital content use processes that are invoiced at a later date. It is preferred to have a system in which the risk for the content provider or the billing company is limited by the fact that the continued use of digital content is inhibited, if the cumulative amount due exceeds a specific limit value. Additional use of digital content is not reinstalled until billing and payment has been made. Card module A third aspect of the invention is that preferably an exchangeable element, such as a module, for example a chip card or a flash memory module, can be used in particular for storing identity information, billing information and information. payment. The mentioned module does not necessarily have to be made as a card; it is also possible to use other shapes, for example, that can be adhered to clothing elements, for example, by sewing or glueing. For simplicity, the term "card module" will be used below; however, it should be understood that this explicitly includes other forms as well. The card module has an interface by which it can exchange data with other devices, in particular a unit of equipment that is convenient and designed to make digital content perceptible to the consumer by sensory means, being that said unit of equipment is referred to in the subsequent "use equipment". This data transmission can be carried out, for example, by cable, by plug-type connectors, connection fields or connection lines. Similarly, the data transmission can be done wirelessly by means of a radio connection, for example, in accordance with the Bluetooth standard, or by magnetic or visual induction, for example, using an infrared connection in accordance with the IrDA standard.

A card module can conveniently be used in conjunction with the inventive solution - for the distribution of digital content, for example, by storing specific item address information, i.e., reference information about network routes through which access can be obtained to digital content, or storing the file that represents the digital content in the module of the card- for billing storing data related to billing in the card module, and to store payment data in the card module which refer to the Payment method and payment route. The use of card modules also makes it possible, in particular, to group contracts, since the card module can be used together with a number of individual equipment units, for which it would be necessary otherwise to conclude separate contracts for use and payment . DRMS A fourth aspect of the invention is that files comprising digital content are preferably distributed in an encrypted form. As a result, it is possible, together with a cryptographic DMRS, to effectively inhibit the unauthorized use of digital content.

With respect to the use of cryptographic DRMS it is necessary to store the key or keys, the cryptographic keys that are necessary to decipher the files legally representing digital content, in a technically convenient manner so that the consumer can use the content that has been distributed in encrypted form. In this context, when using a card module, two cases must be distinguished: - when a card module is used, the multimedia element may, on the one hand, be encrypted in a specific manner for the decoder, not in a specific manner for the card, that is, the card is used to obtain the authorization relating to the decoder, while the data of the files representing the digital content to be used is deciphered by the device of use by the cryptographic decryption keys stored in the decoder, and they become a form that can be perceived by the senses. In that context, the card module preferably offers the authenticity itself for the use of the device by a convenient cryptographic protocol using the data transmission interface. - When a card module is used, the multimedia elements can, on the other hand, be encrypted in a specific way for the card, not in a specific way for the decoder, that is, the card is used to store the cryptographic decryption keys that are required to decipher the digital content, being that it is possible to transmit those decryption keys to the decoder through a conveniently secure connection for data transmission. The data of the files representing the digital content to be used can be deciphered by the device of use by means of the cryptographic decryption keys, which are transmitted by the card module, and converted to a "form that can be perceived by the senses. of flexible charges A fifth aspect of the invention is that the consumer of the digital content is recorded in a finely detailed manner and invoiced fairly, which means in particular that a possibility of providing the consumer with a charge is offered. to the content provider only for those parts of the multimedia elements that it actually uses as well If only part of the multimedia elements are used, it is possible to offer a scheme of charges that also requires only a part of the charges' intended for the use of the whole element Here we distinguish between a level of charge per element, specific to the element, where the invoice It is done independently of the device in accordance with the properties of the element, and a level of equipment charge, specific to the equipment, where the billing is done independently of the element of conformity with the characteristics of the equipment, and hybrid structures of charge level composed of a charge level per item and a charge level per team, where, for example, a higher charge is requested if an element is used in a unit of equipment that allows a better quality of presentation (bigger screen, better sound quality, or similar). Basic instruments for the charge level npor emento are billing by time, for example, audio time used in the case of audio content; invoicing by volume, for example, the number of pages of a text oriented to pages, that have been used; hybrid billing models, for example, billing by volume that is modified to have parts with a schedule of charges for time, in the case of text content oriented in pages. 1 For example, the charge provided for the use of half the volume of the digital content could be set at half the charge provided for the use of the entire content. In the case of digital content in the form of a text element (book), measurements could be taken, for example, with respect to the pages used in relation to the total number of pages. However, other non-linear charge schemes are possible as well. Additionally, this makes it possible to distinguish if the consumer wants to use a multimedia element as many times as he wants, as an element purchased in a conventional manner, once the payment has been made on a single occasion, or if a limitation of the processes of use in terms of quantity, against a significantly reduced charge, it is being considered. It is also possible, for example in the case of text elements, to determine the charge as a function of how many times their individual text pages have been used by the consumer. If the charge for the use of a page-oriented text is calculated exclusively by the process of displaying each page, there is a serious disadvantage that the intuitive search process of "browsing" is billed in an excessively expensive way for the consumer, since that in this process it is possible that a large number of pages will be displayed in a very short time without the consumer having actually been able to use the respective page content, as assumed in that charge model. But if, on the other hand, the charge for the use of a page-oriented text element is calculated purely as a function of time, a slow reader would be at an unacceptable disadvantage compared to a faster reader. An advantageous model of a complex charge scheme can, in particular, provide for a predetermined page charge for each page deployed and a predetermined orientation period can be set, assuming that a page can not be absorbed by the reader until the period has ended. This allows a non-discriminatory browsing function. In addition, a predetermined reading period can be assigned to each page, since it is assumed after its passage it is assumed, in terms of the charge scheme, that the consumer will have been able to absorb the content of the page offered completely. If the period of time, during which a specific page on the screen is consistently displayed after the end of the orientation period is shorter than the predetermined reading period, this system acts, for example, as if the reader had used only a part of the content corresponding to the proportion of the actual period of deployment, in excess of the orientation time with respect to the predetermined reading period. for the proportion of the remaining reading period (residual), the reader is given a credit of time, that is, if the consumer unfolds the page again, a new page usage charge is requested, once the period of guidance has been completed, only if the proportion of accredited residual time has ended. It is also possible to collect all the credits of time that arose due to the premature termination of the reading of a page in a specific credit account of the user. Additional pages can then be granted free of charge against that account. In the case of equipment charge levels, in particular levels that enable charges based on time are possible, for example, a specific unit of individual equipment is enabled for the use of desired items for 24 hours. Even when the aspects presented are related to a technical infrastructure that allows fair and fine-graded invoicing for the use of digital content by the consumer, this of course does not inhibit charging schemes that are based on fixed rates. This is valid both for the unit charge levels and for the equipment charge levels. Billing A sixth aspect of the invention is that the use of digital content is billed on the basis of charge scheme models. For billing, a specific amount that must be paid by a consumer in a currency recognized as a means of payment or a fraction or multiple of other units of value, is determined based on the details of use actions made by the consumer, based on the cargo scheme model respectively applicable. For billing, in particular two aspects are important: on the one hand, it is possible to prepare, for the consumer, a list as an invoice of the processes of using digital content that has been done, for example, during a billing period , from which the consumer can give off how the final amount is composed. - On the other hand, it is possible to produce, for the content provider, a list indicating how often, and if it is correct, also at what level of charge, specific parts of its digital content have been used, and which global charge must be paid to the content provider has been calculated based on this. Accordingly, the inventive solution facilitates the offering of billing service for the use of digital content not only for the consumer, but also for the content provider in a manner based on facts and without fixed fees. Rights of status A seventh aspect of the invention is the storage of data characteristics corresponding to the rights of status and priority ("privileges") that the consumer can acquire by completing use processes enabled and billed when using the card. It is possible, for example, to allow the user to freely use those pages of a text element that he has used frequently enough on the basis of past charge payment. It is also possible to allow the consumer discounts based on previously used processes. Status rights may be assigned, in particular, at the following levels: - specific status rights per consumer, that is, specific status rights are associated with the consumer's identity, or, if appropriate, 'a pseudonymous identity of the consumer, but not to a specific digital content ("element"). An example of this category of status rights are the sales sums that have been accumulated in the past in total and that can be used, for example, as the basis of a discount. - status rights associated with the consumer, specific by element, that is, those status rights are simultaneously linked both to the identity of the consumer or their identity as a pseudonym, and to a file that represents a digital content ("element"). An example for this category of status rights is a specific list of elements that a particular consumer has already used in a particular element of page-oriented text so extensively that in accordance with the scheme of charges is now assigned the right to use the text element without further restrictions and without further billings for use actions. Specific status rights of elements that are associated with consumers can also be associated with a group of elements, for example, all elements that are marketed by a specific content provider, for example, a specific publisher, subordinate status rights that are associated with the consumer and with an element. These status rights are related not only to the identity or pseudonym identity of a specific consumer, but also to a specific part of the item. An example for this category of status rights is the right assigned to a specific consumer to be able to use, from a specific text element oriented to pages, specific individual pages of the item without additional subsequent billing, since a maximum charge, in accordance with The charge scheme has been previously paid for the use of those pages in the past. Status rights form the basis to claim, by the consumer, to which they belong, a specific service that, depending on the circumstances of the individual case, must be provided, for example by the content provider or by the operator of the portal data processing device. The possible service in this context is, in particular: - the payment of amounts of money or other units of value, if appropriate, also applying them against existing charges arising from other processes of use that may already have been made or will be carried out in the future for the consumer; - free use of specific digital content with or without time restrictions; discount for other media consumption actions by the consumer, for example, for cinema visits, visits to festivals, etc., in which case in particular several forms of marketing of a single element may be combined, for example, when a discount for a conventional purchase of a book, if the film is associated with the book has been digitally consummated through the inventive solution; provision of a physical data carrier, with specific digital elements, for example, a CD-ROM with a specific music title, if the aforementioned item has been consummated a sufficient number of times (ie, at least a predetermined amount of processes) in exchange for payment for the use of the inventive solution. The acquisition of status rights by consumption history may occur offline, that is, the device operated on the consumer side determines, on the basis of consumption data, the status right accruing to the consumer by direct reference to the consumer. consumption history, or occur online, that is, the portal data processing device does not determine the status rights accruing to the consumer until after the consumer's consumption history has been transmitted from the device operated by the consumer to the consumer. portal data processing device. In this variant there is the advantage that the consumer is motivated to make online connections for the transmission of the consumption history as frequently as possible. Payment method An eighth aspect of the invention is that, on the one hand, the payment of charges incurred can be adapted to known payment systems that have already been introduced to the market, but on the other hand, payment is preferably possible through technical measures both anonymously, that is, without knowing the identity of the consumer and without the possibility of linking a multiplicity of media use processes through access to a pseudonym, as under a pseudonym, that is, without knowing the identity of the consumer, but with the possibility, through access to the pseudonym, of being able to link a multiplicity of uses propasos of means, as being revealed all the details about the identity of the consumer, that is to say, the name and address of the consumer being revealed. The scope of the inventive solution also includes the possibility of foreseeing, in particular: payment on the basis of an advance payment, that is, the consumer must store a quantity of money before the consumption shares are accepted, since it is not allowed to continue with the use, through technical means of disqualification, as soon as the advance payment has been used, or credit-based payment, that is, the content provider or the operator of the portal data processing device makes a forward provision allowing to the consumer the use of their services without accumulating an advance payment in advance, since the consumer must pay after the invoicing has been made. Also in the case of payments on a credit basis it is possible to foresee technical means of disqualification to inhibit further actions of use by the consumer in the event that a certain amount of payment on credit is pending. In principle, payment processing can be done using conventional channels such as credit cards, debit cards or bank transfer. However, a variant of the inventive solution, where the payment process is performed by interacting with a card module (see the third aspect above), is shown to be particularly advantageous. In that context, the data associated with the payment route that has been agreed with the consumer can be stored digitally in the card module and is used by applying the online payment techniques. Devices with reduced complexity A ninth aspect of the invention is the use of devices of use (apparatuses) with reduced complexity to make digital content perceptible to the consumer's senses. For some time, data processing devices interconnected by Internet or other telecommunication systems have been used not only by companies, but also by final consumers to participate in "e-commerce" in order to carry out commercial transactions of all kinds. The use of the Internet and other telecommunication systems such as, for example, on-line systems patented by the final consumer is almost always done using a personal computer, also called a PC, or a comparable unit of equipment, for example, a computer station. work, a laptop (notebook) or a unit. of mini-equipment that you have in your hand (palmtop). Personal computers and comparable equipment units of this nature have the advantage that the range of functionality that they can make available to the end user is not only determined by the physical equipment used, but can be modified in an extremely flexible way when loading several programs at the desired time. For example, it is then possible to download and install a programming unit, if the end user wishes to use additional functionalities.

The disadvantage of this universality is the increasing complexity of PCs or workstations equipped with operating systems such as Windows or Unix. The end user must first acquire a considerable amount of basic knowledge about the structure and functional relationships of the global complex system to be in a position to use the potential universality offered by the aforementioned system in a practical way, to perform a specific task. It is clear that important groups of end users or potential end users do not want to use, or can not use. telecommunication services, in particular for the purposes of e-commerce, because they do not have the capacity to master the complexity of PCs or comparable units of equipment, whose use so far has in fact been an indispensable precondition for participating in or using the services of telecommunication. The technical problems that are presented to the end user with conventional data processing devices are several. They usually begin with the fact that it is necessary not only to install the operating system, but also to configure it and finally establish a connection with a telecommunication system, for example, the Internet. The modalities of Internet access vary, among other things, depending on the location depending on the country or region and also from provider to provider in the same location. Finally, once a network data processing device capable of being used has been obtained, the end user is confronted, for example on the Internet, with an unsupported abundance of commercial activity offers. In conventional data processing devices, the end user himself must review and acquire extensive knowledge of references in order to be able to use the offers that are of interest to him through the telecommunications network. Finally, if the end user has found a provider with whom he wishes to establish a closer business connection, it is usually necessary to take into account a large number of special features, for each provider associated with the identification and authentication of the clients as well as the delivery of ordered goods and the processing of payments. In view of this problem, it has previously been suggested to offer extremely specialized data processing devices, capable of offering only a single functionality or at most a very small number of functionalities. An example of this is the mobile telephone which is a data processing device connected to a telecommunications network and which serves essentially for a single purpose, that is, to make telephone calls. However, the restriction to a single functionality per type of equipment proves to be a disadvantage given the increasing importance of network data processing devices, since the amount of different types of equipment required for several areas of use increases too much. When there is an increase in the number of functionalities per unit of equipment using conventional procedures, for example, by adding text message calls to a mobile phone, a level of complexity in terms of operator control for the unit is soon reached again. equipment that acts as an obstacle for large groups of users. An important field of application of e-commerce is related to the distribution of files that can include data processing programs, texts, diagrams, multimedia elements or video animations to clients by content providers. In this field of application there is the particular characteristic that the exchange of services between the content provider and the client can be done in a completely virtual way, since both the catalog of the goods and services, as well as the ordering process, the delivery of Goods ordered and invoicing can be processed in the form of data that are exchanged through telecommunication devices. A disadvantage of the previous methods to solve the distribution of elements is that the client usually has to acquire a copy of an element as a purchased element even if he only wants to use it for a short time or only wants to use parts of it. The invention, therefore, refers to a technical infrastructure suitable for such purposes. Telecommunication cards A tenth aspect of the invention is the method where the inventive technical infrastructure for the distribution, billing and payment for content of digital media, including a card module together with SIM cards and similar devices, is implemented in mobile networks of radio communication, for example GSM or UM S. As a result, the functionality of a telecommunication card can advantageously be combined with the multimedia consumption functionality, thanks to the fact that the card serves at the same time as a card module. The advantage offered by this aspect is in particular that the use of such a multifunctional card makes it possible to combine the distribution of digital content through a mobile radio network, the identification and authentication of the media consumer's identity, billing. for the consumption of digital content, possibly with the interaction of a billing server which can be accessed via the mobile radio network, and - the payment of consumed and invoiced digital content, in particular the interaction of telecommunications service providers, in a single application device ("appliance") in a way that is transparent to the consumer. Even if the present invention does not exclude the distribution of digital content through the sale and commercialization of physical data carriers, a virtual transmission is, nevertheless, more important than terms of minimization of business transaction costs. For this, a convenient wide area digital network (WAN) is required. Mobile radio devices constitute, by definition, a means to access a wide area digital network in the form of a mobile digital radio network. Even if the virtual distribution of digital content by wide area networks by cable is also completely possible within the framework of the present invention, wireless transmissions, for example by means of a mobile radio network, seems particularly advantageous, since in that case the consumer You can perform your consumer transactions without being tied to a network infrastructure that is tied to the cable and therefore not available anywhere. The identity or at least the pseudonym of the consumer is known to the telecommunication service provider issuing the SI card. In the case of SIM cards that are used based on credit without the need for a deposited value, the telecommunications service provider must know at least the name and billing address of their client for billing purposes. In the case of SIM cards operating with credit, the telecommunication service provider frequently has information about the specific route of payment, for example, in the form of an open order allowing the aforementioned provider to deduct amounts due from a specific account. . In the case of SIM cards that are issued by the telecommunication service provider as prepaid cards with stored value, charges for the use of digital content may be deducted from the amount of stored value managed by the telecommunications service provider. In theory, services under pseudonym or even anonymous are technically possible in that context.

As regards the territory of the Federal Republic of Germany, it is not possible to issue SIM cards with a pseudonym or even anonymous for GSM networks in accordance with the relevant provisions of the telecommunications law, which are intended to allow authorities authorized to monitor telecommunications traffic without difficulty. However, in other countries this may be different in certain cases. Video on demand A tenth of the inventive solution is the method to offer a specific device is offered for the distribution, billing and payment of digital content as video on demand. This can, for example, take the form of what is termed as "Multimedia set-top box", that is, a converter device between a cable television network and a television set. That "set top box" can also be equipped with a digitizing device for adapting analogue television channels, where the device detects, selects and digitizes the analog signal by representing a television image, for example, by means of what is called a television device. "video capture - frame grabber". Reproduce and order A tenth aspect refers to a particularly convenient solution for ordering and reproducing elements and can be implemented with an independent inventive idea. Conventionally, virtual and similar elements must be selected and downloaded, or transmitted by continuous flow, via the Internet. By broadcasting it is possible to broadcast specific elements in real time in encrypted or unencrypted form at predetermined times and make them available to the consumer when specific conditions are met. However, this involves considerable costs for the content provider when films must be provided, for example, on demand. As in this case the same film must be transmitted at different times through a multitude of channels in order to be in a position to implement the effect "on demand" for the consumer, not only is the air interface exceeded, but also the transmission is still ineffective. The invention is based on the object of only transmitting video material in the form of extracts (trailers) or in abbreviated form with a notice through these channels in order to familiarize consumers with as many elements as possible in a period of time. weather. This is already being done in the case of radio transmissions, since the radio transmitter must earn its money through advertising resources. By means of a convenient technical device on the consumer's side, it is possible to mark the elements making records in the device if there is the possibility of uniquely defined identification, for example, by oral or written information from a presenter, or technically adding a identifier of transmitted elements (analogous to the DaB in radios in automobiles). When marking a specific element, for example, corresponding filters are established in the receiving part of the device. It is possible to transmit the trailers during -days at different intervals. This can be pieces of music (radio), games (shows), movies (video trailers), etc. At a different time or in another channel it is possible, depending on the elements, to transmit them simultaneously by transmitting to a large number of consumers, if appropriate in the same presentation sequence, but this time compressed and encrypted in its full length. The pre-selection device at the consumer's location selects, through the filters, the desired element by filtering out the unwanted elements and recording them in a convenient storage medium which is provided for these purposes. If the user is authorized by the corresponding rights, for example by means of a rights card (smart card), is in a position to consume the recorded elements. The charges are preferably caused only when the elements are used effectively. The elements can also be requested via the Internet or offline, since the elements are then supplied in a targeted manner. Transmission of data causing charges on the part of the consumer A thirteenth aspect of the inventive solution is the method where suitable technical means are envisaged and attempted for the transmission of specific data of person from the consumer field, for example, referring to their habits of consumption, to the operator the portal data processing system or the individual content provider, granting the consumer status rights in exchange for the transmission of data.

in a fourth stage of the method. Fig. 1 shows a schematic view of an inventive network data processing device with a server component 110 and a client component 120. The server component 110 and the client component 120 are connected to each other via a telecommunications network 130 designated as WAN (wide area network), for example, via an analog telephony network, via an ISDN network, via the Internet or via a satellite link for the exchange of data. The server component 110 and the client component 120 typically receive a unique address or an identifier 112, 122, for example, a telephone number, an Internet address, or the like, for the purpose of exchanging data via the WAN 130. If the client component 120 wishes to establish a link with the server component 110 via the WAN 130, requires information about its address 112. Conversely, the server component 110 requires information about the address 122 of the client component 120. The client component 120 is designed to host a mobile card module 140. The card module 140 comprises at least one storage device for non-volatile data storage (not shown) and can exchange data with the client component 120 via a data communication device (not shown). The card module 140 can be configured in particular as a chip card; however, other easily transportable designs are also possible. Basic chip card properties are manifested, among others, in Wolfgang Rankl and Wolfgang Effing: "Handbuch der Chipkarten (Manual chip cards)", Munich: Cari Hanser Verlag, 2nd edition; 1996. The statement in that publication is included in that description by reference. Particularly preferred is a card module 140 which can be used as a chip card printed on both sides. Here, for example, one side of the chip card may be formed by a media content provider who issues that card to his customer. When the card is inserted into the terminal with that face up, a preferred connection is installed to a selection page of that provider. The other side is formed, for example, by the operator of the portal data processing device. If that side of the card is inserted upwards, a connection with a registration and / or search engine of that operator of the portal data processing device is preferably made available, where the aforementioned connection allows elements of Independently of a media content provider. However, on the specific side of the media content provider that occupies one side of the card, there preferably exists at least one link to the operator side of the portal data processing device, so that the user does not have to Remove the card and flip it over, but you can also switch to another provider and media content they offer by checking a link button. The server component 110 is a computer that is typically assigned to a commercial provider of goods and / or services. The serving component 110 can be, for example, a computer that is connected to the telephone network via a modem or ISDN and can be dialed for data communication via a dial-up connection marked from the client component 120. In another embodiment, the server component 110 is a "World Wide Web" server ("WWW server") that is connected to the Internet and that can communicate with the client component 120 via the hypertext transport protocol (HTTP protocol). In another embodiment, the server component performed, for example, as a computer that connects to the Internet and that can exchange electronic mail (e-mail) with the client component 120 via the simple mail transport protocol (SMTP) and via the mail office protocol (POP). The invention is not limited to specific types of telecommunication networks or specific protocols; in that sense, the information provided above is for illustrative purposes only. Fig. 2 shows a schematic view of various aspects of the commercial use of an inventive data processing device. The inventive interaction between a card module 140 and the client component 120 allows the end user (not shown), who is communicating with the server component 110 via the client component 120 to perform advantageous processing of transactions. Aspect (1): On the one hand, the card module 140 facilitates, when interacting with the client component 120, a system-independent configuration of the communication relationship with the server component 110, for example, by a dialing process independent of the system. For that purpose, access data, access configurations or access procedures are stored in the memory of the card module 140. This saves the end user from making a complex configuration of access data, for example, with an Internet access provider, with an email server or with a server for the processing of electronic subscriptions. In a preferred variant, the client component 120 may be configured with the card module 140 so that the end user merely has to introduce the card module 140 to the client component 120 to initiate the installation of the telecommunications link to the component. 110 of server. If shown, the start of the installation of a telecommunication link can be made depending on the activation of an operator control element, in particular of the client component 120 and / or of the capture of a security information element, for example, a PIN. Aspect (2): The card module 140 allows, when interacting with the client component 120, that the end user differentiates and / or identifies with respect to the server component 110. Three cases must be distinguished here: on the one hand there may be cases where it is not necessary or not desirable or legally unacceptable to identify the end user by name, address, etc., but, nevertheless, several end users, each of whom has different card modules 140, it should be possible to distinguish between them in the mentioned cases. This can be done, on the one hand, by merely assigning numbers of a series to the card module 140, for example, by means of a uniquely defined serial number that is recorded in the memory area of the card module 140, which can not over -write, and do not repeat; if the end user successively uses several card modules 140 with different serial numbers, it is not possible to deduce the identity of the end user without additional information about the link. A third variant includes a pseudonym identification of the end user by a multiplicity of card modules 140, however, it does not allow to deduce the identity of the end user without additional information. In the case of prepaid card modules 140, it will often be possible to dispense with the identification of the end user. If payment processing is planned by presenting an invoice, credit card, direct debit, etc., it will generally be necessary to identify the end user completely. A pseudonym is always appropriate if the desired service exchange is to be performed even without the knowledge of the final user identity, but considering the knowledge of the different card modules 140 that should be assigned to the same end user (see also in particular the appearance 7). Appearance (3): The card module 140 also allows, when interacting with the client component 120, the authenticity check relative to the server component 110, i.e., specific authenticity properties of the card module 140 can be verified from the card component. server. Preferably, known encryption methods can be used for that purpose. For example, it is possible to store in a non-volatile memory area (not shown) of the card module 140 - the area being secure against tampering - a cryptographic secret key that is assigned to the specific end user. However, the cryptographic key does not necessarily have to be assigned to an end user in all cases; It is also possible to use these technologies to differentiate modules 140 of cards that have been legitimately put into circulation by an authorized manufacturer of modules, of cards that have been simulated by unauthorized third parties. Aspect (4): Additionally, the card module 140 allows, when interacting with the client component 120, to control transactions that are repeated chronologically with a server component 110, in particular subscriptions for specific services. Appearance (5): In addition, the card module 140 allows, when interacting with the client component 120, the decryption of files specifically for a card module, which can be supplied by the server component 110 and which can represent , for example, program units, text and / or multimedia elements. This offers effective technical protection of copyright.

Aspect (6): The card module 140 also allows, when interacting with the client component 120, that files supplied by the server component 110 can be used which can represent, for example, multimedia elements, in a way measured with respect to time . As a result, a technical infrastructure can be implemented for calculating copyright according to the time of use (see also particularly aspect 7). Aspect (7): The card module 140 also allows, when interacting with the client component 120, to process payment transactions with the server component 110, for example transmitting credit card numbers or digital cash. Various alternatives can be distinguished here: On the one hand, a card module 140 put into circulation can include a specific amount of prepaid credit that is represented by a corresponding predetermined data element that is stored in the memory (not shown) of the module of credit. card. On the other hand, the payment can be made related to the person by presenting an invoice, a credit card or a direct debit, being that the necessary details regarding the identity and the transaction data of the payment (account number, number of credit card, billing address, etc.) are stored in the memory (not shown) of the card module 140. In both cases it is advantageous to protect the authenticity of the card module 140 and the data elements stored in its memory by means of a digital signature that is generated by the legitimate office issuing it. Regardless of the previous distinction between prepaid credit and continuous billing, there is an alternative between acquiring files in accordance with the purchase principle, that is, once the purchase price has been paid there is the possibility of chronologically unlimited use, and invoicing in accordance with the intensity of use, measured, preferably, by the use of time or the volume of data actually used in a file. Finally, there is the additional independent alternative between card modules 140 which, even at the time they are put into circulation, have already been provided with all the necessary data elements related to billing and card modules 140 where the related data items with the billing they are not transmitted by the memory service component 110 (not shown) of the card module 140, until the said card module 14 has been issued to the end user. The eight individual cases that originate from the combination of these three alternatives each condition a particular technical execution of the card module and its interaction within the scope of the inventive solution. Aspect (8): If the card module 140 is provided with sufficient memory capacity, for example in the form of what is called instant memory, files representing, for example, programs for data processing systems, texts or multimedia elements they can be stored temporarily or permanently in the card module. As a result, the technical implementation of systems already mentioned in aspect (4) for the automated periodic acquisition of programming units, text and / or files that represent multimedia elements and that are distributed through a component is improved in particular. 110 of server. Aspect (9): Finally, the card module 140 may be used when interacting with the client component 120, to enable or disable features specified by the server component 110 telematically. In an inventive data processing device, it is not necessary to implement all aspects simultaneously. Exemplary executions and their variants described below make use, to some extent, of specific cryptographic techniques, such as, for example, asymmetric cryptography and digital signatures. An introduction to applied cryptography can be found, for example, in Bruce Schneier: "Applied Cryptography", New York: John Wiley & amp;; Sons, Inc., 1994. What is stated in that document is incorporated by reference to the present description. Fig. 3 shows a first application of the invention through a schematic view of an inventive data processing device. As already shown in Fig. 1, a client component 120 is connected via a WAN 130 to a server component 110. The client component 120 is provided with a display device 125 which is shown only schematically. The card module 140 that is hosted by the client component identifies a specific end user (not shown) to whom the card module 140 has been assigned, either personally or by a pseudonym. In particular, an identity information element 141 that can be transmitted to the server component 110 via the WAN 130 is stored in the card module 140. The identity information 141 may additionally be secured in the usual manner on pages of the client component 120, for example, by a PIN or by a biometric identity detection device (not shown). In addition to the identity module 140, there may be other card modules 140a, 140b, 140c to which the identity SN1, SN2 and SN3 are assigned. If the card module 140 associated with the identity SN4 141 is replaced with one of the other card modules 140a, 140b, 140c, the respective assigned identity information SN1, SN2 and SN3 can be transmitted to the server component 110. The first inventive application illustrated in Fig. 3 is particularly significant to differentiate a person in action at least with respect to his? feature, for example, as part of the contract with respect to server component 110, or otherwise be able to identify it directly or by means of a pseudonym. Fig. 4 shows a second application of the invention through a schematic view of an inventive data processing device. As already shown in Fig. 1, a client component 120 is connected to a server component 110 via a WAN 130. The client component 120 is provided with a display device 125 which is shown only schematically. The card module 140 that is hosted by the customer component can identify a special contract relationship AbD 141, in particular by a predetermined data item, where the aforementioned relationship comprises in the present example the regular supply (subscription) of a product. digital multimedia. In addition to the card module 140, other card modules 140a, 140b, 140c may also exist, to which the contractual relationships AbA, AbB and AbC (141a, 141b, 141c) were assigned. If the card module 140 associated with the contractual relationship 141 is replaced with any of the other card modules 140a, 140b, 140c, the respective contractual relationship .141a, 141b, 141c can be transmitted to the server component 110. The contractual relationship information 141, 140a, 140b, 140c typically varies with the controls of an automated file selection process (not shown) that must be transmitted from the server part 110 to the client component 120 and represents a representation multimedia, as well as regarding the transmission time. Fig. 5 shows a fourth application of the invention through a schematic view of an inventive data processing device. As already shown in Fig. 1, a client component 120 is connected to a server component 110 via a WAN 130. The client component 120 is provided with a display device 125 which is shown only schematically. The card module 140 that is hosted by the client component identifies, in particular, a specific server component 110, which may be assigned, for example, to an associated specific service provider SPr4. In addition to the card module 140, other modules 140a, 140b, Card 140c may also exist, each assigned to a service provider SPrl, SPr2 and SPr3 (141a, 141b, 141c). If the card module 140 associated with the associated service provider 141 is replaced with any of the other card modules 140a, 140b, 140c, the respective service provider information 141a, 141b, 141c can be transmitted to the server component 110. The service provider information 141, 140a, 140b, 140c typically varies with the controls of an automated selection process with respect to the data transmission parameters of the client component 120, so that the automatic initiation of data exchange between the client component 120 and server component 110 becomes possible. Fig. 6 shows a first variant of an execution of the inventive solution illustrated in Fig. 1. As already shown in Fig. 1, a client component 120, designed to house a card module 140, is connected to a component 110. of server via a WAN 130. The client component 120 is provided with a display device 125 which is shown only schematically. Fig. 6 in this way shows a solution where the client component 120, which is designed to house a card module 140 and the display device 125 form a unit of equipment that is essentially physically carried out in a single unit. Fig. 7 shows a second variant of an execution of the inventive solution shown in Fig. 1. As already shown in Fig. 1, a client component 120, designed to house a card module 140, is being provided. The client component 120 is connected via a data communication device 123 to a display device 125 which is shown only schematically, and which is connected to a server component 110 via a WAN 130. Fig. 7 in this way shows a solution where the client component 120, which is designed to host a card module 140 on one side, and the display device 125 connected to the WAN 130 on the other, each independently form a unit of equipment that is performs essentially in a unit in physical terms, where the data exchange between the client component 120 and the display component 125 is performed by the data communication device 123. Wireless and wired devices and methods, particularly by a data transmission cable (not shown), by radio (not shown), by infrared light, for example, IdDA (not shown), are possible technical implementations of the device. data communication. Fig. 8 shows a third variant of an execution of the inventive solution shown in Fig. 1. As already shown in Fig. 1, a client component 120, designed to host a card module 140, is connected to a server component 110 via a WAN 130. The client component 120 is connected via a communication device 123. to a display device 125 shown only schematically. Fig. 8 in this way shows a solution where the client component 120, which is designed to host a card module 140: and is connected to the WAN 130 on one side, and the display device 125 on the other, each they form in themselves a device that is carried out essentially in a unit in physical terms, wherein the data exchange between the client component 120 and the display component 125 is carried out by the data communication device 123. Wireless and wired devices and methods, particularly by a data transmission cable (not shown), by radio (not shown), by infrared light, for example, IdDA (not shown), are possible technical implementations of the communication device of data. Fig. 9 shows a fourth variant of an execution of the inventive solution shown in Fig. 1. As already shown in Fig. 1, a client component 120, designed to host a card module 140, is connected to a server component 110 via a WAN 130. In addition to the client component 120 there is a display device 125 shown only schematically and which is designed to accommodate at least one card module 140. Fig. 9 thus shows a solution, where the client component 120, which is designed to house a card module 140 and is connected to a WAN 130, on one side and the display device 125 on the other, each in which case a unit of equipment can be realized essentially as a unit in physical terms, where the exchange of data between the client component 120 and the display component 125 is performed upon reinserting the card module 140. For example, the card module 140 may be housed in the client component 120 in order to store data that is supplied by the server component 110. Once the respective data has been recorded in the card module 140, this data can be displayed in a perceptible way for the senses upon reinserting the card module in the display device. It is also possible, conversely, for example, to store data related to ordering processes in the card module 140 when it is housed in the display device 125. Once the card module 140 is inserted back into the client component 120, this sorting data can be fed into the server component 110 via the WAN 130. Fig. 10 shows a fifth variant of an execution of the inventive solution that is shown in Fig. 1. As already shown in Fig. 1, a client component 120 is provided, designed to house a card module 140. The client component 120 is connected via a data communication device 123 to a display device 125 which is only schematically shown and is connected to a server component 110 via a WAN 130. Fig. 10 shows a solution in this way, where the client component 120, which is designed to house a card module 140 and the display device 125 that is connected to the WAN 130, on the other, each in itself forms a unit of equipment that can be realized essentially as a unit in physical terms, where the data exchange between the client component 120 and the display component 125 is performed by the data communication device 123. Wireless and wired devices and methods, particularly by a data transmission cable (not shown), by radio (not shown), by infrared light, for example, IdDA (not shown), are possible technical implementations of the communication device of data. The client component 120 shown in Fig. 10 is designed to accommodate a multiplicity of modules 140a-14Oe of cards which can independently initiate and control each other communication processes with the server component 110 via the card module data (not shown) which are stored in the mentioned card modules 140a-140e, and which can be selected independently from each other, from the point of view of the server component 110. For example, at least one of the card modules 140a-140e can act as a component of a system as a memory for digital multimedia products that are supplied in digital form by the server component 110 via the WAN 130, so regular but asynchronous with respect to the acts of operator control of the user. The particular feature of the arrangement shown in Fig. 10, in comparison with the arrangement illustrated in Fig. 7, is in particular the fact that a master card module 140 is supplied with which the display device 125 can identify and verify its authenticity. in a particular manner with respect to the client component 120 and the other card modules 140a-140e can be inserted therein. For example, the master card module 140 can be inserted into a digital book that is used as a display device 125. The digital book is then configured by the master card module 140 so that, relative to the client component and the additional card modules 140a-140e inserted therein, specific privileged operator control transactions, for example, enabling or disabling the client component 120 for provisioning by the server component 110 or services ordering transactions with respect to the server component 110, may be performed by the user g the data communication device 123. For this purpose, the data communication via the data communication device 123 is preferably protected against intrn and manipulation by suitable technologies, in particular cryptographic technologies. Fig. 11 shows a sixth variant of an execution of the inventive solution shown in Fig. 1. As already shown in Fig. 1, a client component 120 is provided, designed to house a card module 140 and designed to hog a card module 140 and connecting to a server component 110 via a WAN 130. The client component 120 is connected via a data communication device 123 to a display device 125 which is shown only schematically and is connected with a server component 110 via a WAN 130. Fig. 11 also shows in this way a solution, where the client component 120, which is designed to host a card module 140 and the display device 125 which is connected to the WAN 130, on the other hand, each one forms in itself a unit of equipment that can be realized essentially as a unit in physical terms, where the exchange of data between the client component 120 and the display component 125 is performed by the data communication device 123. The particular feature of the arrangement shown in Fig. 11 with respect to the arrangement shown in Fig. 7 is in particular the fact that the client component 120 is designed, as also shown in the case of Fig. 10, to accommodate a multiplicity of cards 140a-140e of card which, by means of the module card data (not shown) stored therein, can respectively initiate and control communication transactions with the server component 110 independently from each other and which can be independently selected from each other of view of the server component 110, during communication transactions that are initiated by the server component 110. For example, at least one of the card modules 140a-140e can act as a component of a system (shown in Fig. 4), ie a card module or a plurality of card modules serve as memory for digital multimedia products which are supplied in digital form by server component 110 via WAN 130, in a regular but asynchronous manner with respect to user operator control transactions. In the variant shown in Fig. 11 it turns out to be advantageous to implement the client component 120 as a fixed card module station which is essentially permanently connected to the WAN 130 and which can thus initiate data communication transactions in relation to the server component 110, and that in addition can receive data communication transactions initiated by the server component 110 asynchronously with respect to user usage transactions, even when the display device 125 is made as a mobile device, that the user carries on his person even when he is not present at the location. Both relative to the variant shown in Fig. 10 and relative to the variant shown in Fig. 11, it may be advantageous to realize the display device 125 so as to house at least one card module 140., so that the mode of use shown in Fig. 9 can be used when inserting a card module again. While the client component 120 is designed to house at least one card module 140 in the variants shown in Figs. 6 to 11, Figs. 12 and 13 each show a variant where the client component 120 is used without a separate card module. Fig. 13 shows a client component 120 that is designed to host a complete display device 125, the display device 125 being, in turn, designed to accommodate at least one card module 140. Data communication is performed between the server component 110 and the card module 140 in a manner where the exchanged data is passed through the display device 125 by convenient electronic means. Certainly, it is not absolutely essential that the client component 120 be designed to accommodate a complete display device 125. The exchange of data between the client component 120, on the one hand, and the display device 125 that is designed to host at least one card module 140, on the other hand, can, for example, also be implemented as shown in FIG. Fig. 13, by the data communication device 123. Wireless and wired devices and methods, particularly by a data transmission cable (not shown), by radio (not shown), by infrared light, for example, IdDA (not shown), are possible technical implementations of the communication device of data. Figures 14 and 15 show further variations of an execution of the inventive solution shown in Fig. 1. As already shown in Fig. 1, a client component 120 that is designed to host a card module 140 and that is connected a server component 110 via a WAN 130 is also provided in Fig. 14. A display device 125 is also connected to the AN 130a. The WAN 130 may be identical to the AN 130a. An interaction - initiated by the display device 125 and transmitted via the WAN 130a - with the server component 110, causes multimedia data from the server component 110 to be transmitted to the client component 120 via the WAN 130. As a result, the user (not shown) can call, for example when traveling, server component 110 data that is transmitted via WAN 130 to client component 120 that is installed, for example, in the house. Fig. 15 shows a variant where the client component 120 is provided with a display device 125. The data (not shown) that is called in the server component 110 is transmitted to a client component 120a via WAN 130. FIG. 16 shows a schematic diagrammatic view of an inventive device 100 for distribution, billing and payment of digital media content. Files 104, 106, 108 that are made available by content providers 102 are stored ready for distribution on a server 110. The distribution of the files to the individual client computers is preferably done in encrypted form via download via the Internet or through sales and marketing of physical data carriers such as CDs, DVDs, instant memories, etc. (not shown). Here, by marking a service provider, you can select specific item formats using the customer's computer or playback device, for example, an MP3 player is provided only with MP3-compatible elements for download. Through a personal computer or a laptop or a television with an Internet connection it would be possible to see all the formats of elements that can be enjoyed using specific classifications to select and order them (download, upload, streaming or broadcasting). He digital content that is made available to the client computer is symbolically represented and marked with the reference symbol 112. Billing and payment of the charges for those digital contents 112 are performed by an exemplary functional block 120. The functional block 120 has a decoder 122 that first decrypts (reference symbol 124) the digital content cryptographically and then makes it accessible in a technically convenient manner to the sensory perception by the consumer 128. In the case of MP3 audio files, this can be done, for example, by generating an analog audio signal that can be reproduced by a speaker 126 or a headset (not shown). In the case of other content (for example texts, images, vines); not illustrated) there may also be, for example, a visual display or a display device n (not shown). An evaluation device 130 is connected to the decoder 120 in order to continuously generate data for a consumption record 132, while the consumer 128 is using the means, where the aforementioned data describe the respective usage process with sufficient precision so that Billing can be done later. The consumption record comprises, for example, data about the duration of use of an audio title or, in the case of other element formats (for example text, not illustrated), it also contains data about the text pages used and the time of individual use with respect to individual pages of text. Other options to record or measure usage are also possible. A limiter 134 is also provided to allow the calculation of the total charge that accumulates in accordance with the data in the consumption register 132, continuously or at specific time intervals as a function of the consumption record, and to transmit a signal 136 of disabling the decoder 122 when a predetermined total load is exceeded. As soon as the decoder 122 receives the disabling signal 136 from the limiter 134, the use of encrypted content 112 is interrupted until the limiter 134 cancels the disabling signal 136. Instead of a total charge, time credits or credits are also possible in terms of volume of use. A hybrid variant of the possibilities described above is also possible. A stored value memory 140 stores a data value representing a sum of money, an available time of use, or a volume of available use that the consumer 128 has stored to cover sums of future bills, for example by prepayment in form of a deposit. The stored value memory 140 can be updated by all the usual payment microsystems. These include, for example, "click and buy - check and buy", "paysafe - secure payment" (prepaid) or uploading by a service number, such as a number 0190. When the saved value is loaded by a number 0190 it is possible, for example, to charge specific amounts of stored value through different telephone numbers that can be configured as terminal numbers for a master number, and that these amounts are billed by the telecommunications companies. Loading a stored value memory, in particular for off-line use of digital elements, programs or the like, by means of a service number is an independent inventive idea for which protection is claimed independently. In particular, charging a stored value memory to a payment module that can be connected, for example a smart card, by a service number, is advantageously possible. This saved value may in turn be a value saved in terms of money, a time credit or a volume-related credit. Rights of use and / or specific privileges of elements can also be configured by means of a service number. The limiter 134 preferably fulfills its function by interacting with the stored value memory 140, that is, while there is a stored value, the decoder 122 is not blocked. The functional block 120 contains critical data and functions that must be protected against any unauthorized manipulation from the outside, in particular by the consumer. The decoding key 123 by which the decoder 122 cryptographically deciphers the data 112 representing digital content, facilitating further processing, is particularly sensitive. The saved value amount (not shown) stored in stored value memory 140 is also highly sensitive. The means 130 for measuring the consumption and the limiter 134 are critical functions because the attempted billing of charges can be sabotaged by manipulating these devices. It is therefore advantageous to configure the block 120 functional as a particularly protected assembly (safe against intervention). In the simplest case, the individual elements of that assembly 120 can be wrapped, for example with a sealing compound, for example a synthetic resin. In further development solutions it is possible to provide sensors (not shown) that have the ability to detect unacceptable mechanical and / or electrical manipulations. The output signal of these sensors can then be used to instantly delete critical data such as cryptographic keys 123 or amounts of values stored in stored value memory 140. The components of the stored value memory 140 and / or the limiter 134 are combined in the exemplary embodiment shown in FIG. 16 to form a functional block 120, they can also be housed in a separate module or in separate modules that can be connected to the functional module 120. All the components that are combined in the functional module 120 can be implemented either as separate components of physical equipment or as individual programming modules or also as complete programming solutions, for example, in the form of extensions (plug-ins) for a browser. The consumption register 132 also represents an accumulation of sensitive data that must be protected against tampering. To do so, the memory (not shown) for storing the consumption record 132 may also be included in the protected functional block 120 (not illustrated). Another possibility is to protect the data values of the consumption register 132 against unauthorized changes by one or more digital signatures. To do so, a component for generating and testing digital signatures (not shown) that is advantageously provided included in the 12.0 protected critical functional block. When the mandatory billing and payment process is performed, the data content of the consumption record is preferably transmitted in a convenient way through a network data link, cryptographically protected against surveillance and manipulation of unauthorized data, to a server 145 billing. The billing server calculates, with reference to the data of the consumption record, the charges that must be paid by the consumer and deducts the corresponding amount, for example by means of a charge transaction of an account 150 (fictitious) that is assigned to the consumer. The consumer can then perform the payment transaction in a conventional manner, for example, by transferring money or through a clearing house for credit cards. Account 150 is not mandatory; if payment systems are used that do not require a 150 (fictitious) account, such as anonymous digital cash, it is possible to dispense with account 150. Once the payment is made, or given the appropriate solvency of the customer, also after the invoicing by the billing server 145, the amount of stored value stored in stored value memory 140, may be increased by a specific amount of stored value by transmitting a stored value message 155, cryptographically protected against tampering, from billing server 145 to the functional unit 120, or the stored value memory 140. The stored value memory 140 is preferably arranged in a smart card in order to be able to use the stored value stored independently of the system and in a mobile manner, even in other equipment units. The functional module 120 contains in that case a smart card reader (not shown). The component containing the smart card reader can be realized, for example as a PCMCIA card having the functions of the functional module 120. An alternative (not shown) to Fig. 16 is that a module that can be coupled to a playback device can be plugged, for example PCMCIA, into a built-in memory in which, among other aspects, so-called player and / or reproduction licenses may be stored so that when connecting the module to another playback device or computer, the license with the corresponding rights of reproduction or rights of use may be used and may not be returned unusable or invalid when using another playback device. Here, existing license solutions from other providers can be easily modified and / or the module can be provided with convenient measures to facilitate use independently of the license system or the player or player licenses and / or the provider element through the module , but it is not possible to produce one of licenses, rights or amounts of saved values. In another implementation (not shown), means are used to configure a smart card as rights card so that it is possible, when interacting with a license of a programming package installed on a computer, to correspondingly reproduce multimedia data (elements ) provided. Here, in particular information to identify and / or verify the authorization to use the license, the player and / or specific elements is provided by the smart card. In a further development, a license of a programming unit or a player can be modified so that different users can use elements or application programs, etc., which are made available through a separate smart card, without having to install a new one. license on the computer or playback device. Payment by smart card is possible, for example by means of money units, by applying them against credit of time and / or credit in terms of usable volume of data. It is also possible to make the smart card as a debit card and / or credit card. Fig. 17 shows a schematic block diagram illustration of a detail of the device shown in Fig. 16. The server 110 makes digital content available (not shown) and can be connected to the protected functional block 120, for example, by a 210 wide area data network (WAN) via a modem 212. The functional block 120 is then connected to a playback device and has a browser / toilet 1500 that can also be made as an extension to an existing browser and has capacity also to represent status information regarding the units consumed, times and prices or remaining amounts of value saved in addition to the deciphered data. Instead of a modem, another convenient network function device can be used, for example for ISDN, GSM or ÜMTS. Specific details of Fig. 16, as in particular the means 130 for mediating the consumption, the limiter 134 and the stored value memory 140, are not shown in Fig. 17. In Fig. 17, a card module 215 is being provided. which can optionally be used as a rights card and control card to control the decoder 122, where the card is preferably made as a smart card. Fig. 18 shows a schematic view of a first exemplary system architecture of an inventive device for distribution, billing and payment of digital media content. A device for use for the use of digital content by a consumer is designated with the reference symbol 310. The device 310 of use can be provided with a connection device for connection with a card module 315. A media server 320 maintains content files 330 which contain respective digital contents and charge schema information. The media server 320 can be connected via a network data link 340, preferably via the Internet, to the user device 310, in particular to download content files 330. Individual digital content providers can operate 350A, 350B, 350C servers that connect via respective 352A connections, 352B, 352C of data networks, for example via the Internet, to the media server 320. In the arrangement shown in Fig. 18, it is the responsibility of the providers 350A,, 350B, 350C to keep available 354A, 354B, 354C files with digital content and 356A, 356B, 356C information of charge schema. If a specific digital content is requested by a consumer (not illustrated) by the use device 310, the provider 350A, 350B, 350C of content of the file 354A, 354B, 354C of corresponding content 5 it assigns information 356A, 356B, 356C of charge scheme and transmits the files 354A, 354B, 354C to the media server 320, from where it can be transmitted to the user device 310 for use by the consumer. Fig. 19 shows a schematic view of a second exemplary system architecture of an inventive device for distribution, billing and payment of digital media content. In the variant of the arrangement of Fig. 18 shown in Fig. 19, categories 322A, 322B, 322C, 322D of predetermined rates are configured in media server 320, and providers 354 ?, 354B, 354C of content files stipulate the Charge scheme model valid for each of the content files by virtue of the fact that the transmission 352A, .352B, 352C, 352D is performed in a specific manner by files to an area 322A, 322B, 322C, 322D of the server 320 of media that is classified according to the categories of cargo schedules. Fig. 20 shows a first diagram associated with the explanation of the dependence of the volume received by the consumer - from pages of a text document oriented to pages (not shown) on the vertical axis with respect to the time of use, used for this page, on the horizontal axis. Here, the scale of the vertical axis must be understood in such a way that a page of text that has been read several times counts also in the measure as it corresponds to those several times. The number of pages of the text assumed in the illustrated example is 120 pages. Assuming a constant reading speed, for example the reading curve that is called C, has a low steepness and where each of the 120 pages of the item has been read once by the consumer after approximately 15 hours of time. Reading is obtained for a slow reader as an example. Correspondingly, the reading curve, for example, which is designated B and which has a high degree of steepness and where each of the 120 pages of the item has been read once by the consumer after approximately 4 hours of reading time , it is obtained from a quick reader, as an example. Finally, for example, the reading curve that is called A and that has a low degree of steepness and where each of the 120 pages of the element has been read once by the consumer after approximately 7.5 hours of reading time is obtained for an average reader, like example. With respect to the reading curve A, the charge scheme is selected so that the distance from the zero point to the point where approximately 240 pages have been read by the consumer after approximately 15 hours is assigned a charge amount of DM 6.00. Correspondingly, reading the item once costs DM 3.00 in approximately 7.5 hours. Fractions or multiple of this can be invoiced proportionally accordingly. Fig. 21 shows a curve diagram referring to the explanation about the dependence between the intensity of use of an element and the assigned price. While in the diagram shown in Fig. 20 the charge increases proportionally with the number of pages read, alternately, in Fig. 21, diagrams of non-linear charge curves are shown. In this respect, in the example shown "sensory elements" as texts of "high" literature are distinguished from "functional elements". In the case of sensory elements, it may be desirable, in view of commercialization considerations, to charge for the use of digital content by a corresponding technical infrastructure so that the first quantity components of the item's use by the consumer are billed to a lower load, so that the consumer can orientate, without concern in terms of expectation of high usage charges, and is motivated to continue consumption. Correspondingly, it may be desirable with functional elements to adopt a charging scheme for the use of digital content by means of a technical infrastructure so that the first components of element usage amount are billed at a higher charge compared to the use of backs of the element by the consumer, since the information that is extracted from the item by the consumer at the beginning often represents, at a subjective level, the most important utility value for the consumer. Fig. 22 shows a first diagram related to the explanation of the dependence of the volume - received by the consumer - of a page of a text document, of the time of use spent when using the page. The time that the consumer takes to read a single page of the text-oriented element is graphic on the horizontal axis. The percentage of the amount of text already read by the consumer with respect to the total amount of text on the page is represented on the vertical axis. The reading curve plotted in the diagram shown takes into account a certain time of orientation, for example, 15 seconds, that is to say for all the moments during the lapse between 0 and 15 seconds it is assumed that the reader has not absorbed reading material in degree, substantial some. At a time ti + t2 which is taken as an example, in the present example therefore after 2 minutes and 53 seconds, it is assumed that the reader has read approximately 75% of the amount of text on the text page under consideration After a total time of ti + t2 + t3 of 3 minutes and 45 seconds, the page has been read completely. The invention makes possible, for example, in particular a charge scheme where a page-oriented text element is invoiced as a function of the volume, with a single page displayed on the screen not being calculated immediately after it has become visible. Instead, during the orientation period (0, tl), it is considered that the page under consideration has not been used in terms of the charge schema and - it is not invoiced at all. It is considered that the page has been fully used by the consumer in terms of charge scheme only after the predetermined period ti + t2 + t3. Fig. 23 shows schematically and exemplary time profiles for the use of a page of a text element oriented to pages by a consumer for a methodological charge scheme shown in Fig. 22. The rectangle symbolizes, in the guise of example, the same page of a page oriented text element; here a page with the page number 21. After the page has been displayed on the display device, the page is not considered as being in use during the orientation period, for example, 15 seconds (Fig. 23?) . After the orientation period has ended, the full price is billed for the use of the page, for example, D 0.025, even if the user has received only a fraction of the text content of the page. The period of time during which this page is displayed on the screen is continuously recorded (Fig. 23C). Assuming that the reader completes the display of the respective page after 15 seconds starting from the beginning of the use causing the page's charge after finishing the orientation period, moving to another page (in the example to page 36), interrupting the use of the respective element, or even _ turning off the display device (Fig. 23D), the time of use saved for this page until now remains pending. A charge-free orientation period is assigned for 15 seconds for orientation on the new page 36. If the consumer then causes the same page 21 to be displayed again at a later time (Fig. 23E), a new one is assigned first orientation period. After completing the new orientation period (Fig. 23F), time billing continues to take into account the time already spent cumulatively viewing this page by the consumer in the past. If the predetermined time for a single use of the page has expired, it is considered that the page has been read completely (Fig. 23G). There is no more billing based on time while the page is still displayed without interruption on the screen (Fig. 23H). Instead of individual storage periods of use started by specific pages, it is easily possible to also manage a time credit account where unused time is accumulated from all the prematurely interrupted pages and it is made available to the user to view the same page or another, completely new. Figure 24 shows a second diagram related to the dependence of the volume - received by the consumer - of a page of a text document, on the time of use used to use the page. Here, the reading curve shown in Fig. 24 corresponds to the read status of the page shown in Fig. 23C. Fig. 25 shows a third diagram related to the dependence of the volume - received by the consumer - of a page of a text document on the time of use used to use the page. Here, the reading curve, shown in Fig. 25 corresponds to the reading status of the page shown in Fig. 23H. Fig. 26 shows a schematic view of the reading process with obtaining status rights. The charge scheme options made possible by the invention comprise in particular cargo model models where, in the case of a page-oriented text element, status rights can be acquired and presented conveniently in terms of computer technology at the level of an entire element and / or the level of a page. For example, the complex volume / time billing mode shown in Fig. 20 to 25 makes it possible for the consumer to receive a credit for residual components of read time that is related to the respective pages. This is symbolically indicated in Fig. 26 by the fact that the components of time consumed per page are represented in a hatched form, while the remaining residual time components are not shredded. Additionally, rules describing the transition from a volume-oriented billing system to a time-oriented billing system, or a complex volume / time billing system to a targeted billing system can be predefined on the provider side. in the purchase. For example, for a specific element (identified in Fig. 26 with an identification number 2349457) it is possible to predefine that after reading twice, the reader obtains the right to use chronologically unlimited without obligation to pay more charges. In Fig. 26, other possible rules for charge schemes are presented in a merely symbolic way, for example, rules that apply a scheme of charges of inverse progression, or that the content can no longer be used after being read twice. Fig. 27 shows a schematic view of an inventive device with a card. A first device for use and billing for the use of digital content and a second device for use and billing for the use of the aforementioned content are designated respectively with reference 1292 and 1204. The distribution server 110 is connected via the data exchange network 210 (WAN) to devices 1202 and 1204 to download files that are available on the server and that have digital content that is offered for consumer use (not shown). It is understood only that these files can be transferred to the consumer for use by devices 1202 and 1204 by exchanging physical data carriers (eg, CD, CD-ROM, DVD, etc.). The devices 1202 and 1204 each have a respective device 1206 and 1208, for housing a card module 1210. Each of the devices 1202 and 1204 also has a design corresponding to the details shown in figures 16 and 17, that is, a particular decoder 1212 and 1214 is being provided in particular. The other components necessary for billing, as means for measuring the Consumption, limiter, stored value memory and consumption record are not displayed. Fig. 27 shows, on the other hand, that the consumer (not shown) uses through the device 1202 an element with an identification element 333 and in doing so has used a total of. 420% of, that is more than four times, the volume of the element. The privileges obtained with the repeated reproduction of the element 333 are stored here in the card module 1210. If the user changes to another device 1204 (in the middle of the right side in figure 27) and again requests the element that is not present in the device 1204, with the result that the element must be made available again by the server 110 via the WAN 210, this is encoded differently for the decoder B. The privileges obtained, however, are made effective by inserting the card module 1210 into the device 1204, with the result that, depending on the schematic model of charge, the new reproduction of item 333 is 1 5 consider, for example, cumulatively progressively the other way around, for example, when you reach 600% when you finish, and invoice accordingly. The example in figure 27 shows that the same element can be made available in different ways by encryption in different devices and, however, it can be selected by the same card module 1210. Fig. 28 shows a schematic view of a scheme for managing and transmitting rights by means of a card module. Figure 28 shows that the same card module 1210 can select digital media content from one or more servers in different playback devices in different formats. As a result, the card module 1210 is shown on the left side in conjunction with an MP3 player to reproduce sound or music signals, in the middle part it is inserted into a digital multimedia reception system, or a television set or some other terminal connected to that, in order to visualize video signals, and the right side in conjunction with an electronic book reader to display text pages and / or image pages. Fig. 29 shows a schematic view of another scheme for managing and transmitting rights, by means of a card module. In particular, there is an illustration here of encryption related to the module that facilitates the making of telephone calls and transmitting data online, and consuming them offline. The user requests an item from a multimedia content provider CPrl via his telecommunications service using a telecommunications module (eg GSM or UMTS) which is provided with a rights card. The rights card is additionally provided with a cryptographic encrypted module whose type of key is known for the telecommunications service. The multimedia content provider CPrl as a logistical partner of the telecommunications service ascertains with the telecommunications service, using the telephone number of the end user, which key must be used for that telephone number and transmits the element directly to the end user together with the corresponding cryptographic encryption . The end user can consume the item only by using the rights card with the corresponding decryption module, or in continuous flow mode live or offline in display mode. Billing is done via the telecommunications service. A device for use and billing for the use of digital content is designated with reference 1410. An IT infrastructure of a telecommunications provider is designated with the reference symbol 1415. Technical IT infrastructures of the content provider of files with digital content ( multimedia) are designated with the references 1420A, 1420B, 1420C, or 1420D. Fig. 30 shows a flow diagram for a discharge process together with Fig. 31 shows several possible solutions for implementing the invention. In the simplest and least reliable case, the cryptographic encryption of the media files and the user data and the data of the charging scheme is done in a conventional PC through a solution of a programmatic unit. In order to increase the reliability, the mentioned PC can be further communicated with a signal solution, for example, a chip card. The highest level of security is achieved with an integrated terminal that is encapsulated as far as possible (solution at the device level, for example an MP3 player), where opening it causes the data to be lost. Mobile universal device Fig. 32 shows an advantageous mobile digital device in a particular execution as computer 127010 as a clothing element, which can be used in particular as a multimedia player, preferably including a digital rights management system (DRMS). The mobile device 127010 may have aperture 127020 for PCMCIA that can be used in particular to house a smart card chip card, for example, for distribution and payment systems. The PCMCIA interface can also be used for other functions, for example, for adapter cards for smart media modules or similar storage cards, processor cards or other expansions of programming and / or equipment packages. It is then also possible to provide the mobile device 127010 with a mobile telephone function, for example, WAP, SMS, GSM, GAPS, ÜMTS. An execution comprises a PCMCIA card as a decoder module for digital rights management with integrated memory, smart card reader and / or means for making telephone calls and / or data transmission / data communication using WAN (GSM, UMTS, GPRS etc.). ). Additionally, it is convenient to offer usual functions for a personal digital assistant (PDA) such as appointment planning, notes, etc. These can also be implemented in the mobile device 127010 itself, in the display and operation control part 127030 or in a connection module, for example 127020. All functions can be used, if appropriate, individually or in combination. Other functions are possible too. The stated content of PCT / EP 01/03738, in particular the description of particular executions of computers as items of clothing, is declared with this mention explicitly object of the present patent application. Reference 127030 denotes a display unit and operation control. The 127030 display and operation control unit has a 127040 screen that is used to display texts and graphics, including videos, of the applications running on the mobile 127010 device. The connection between the mobile device 127010 and the operation monitoring and display unit 127030 can also be realized by a cable (not shown), but a wireless data communication connection is preferred, for example, by radio waves, using, for example, example, Bluetooth standard, or infrared data transmission, for example, the IrDA standard. The display and operation control unit 127030 can advantageously also be provided with a subordinate audio system, for example a 127050 hearing aid / microphone combination. In order to listen, it is also possible to use, for example, a high-fidelity headband. In another variant (not shown) the microphone can be integrated into the display and operation control unit 127030. The display and operation control unit 127030 is conveniently sized so that it can be held comfortably in the hand. If the 127030 unit of visual indicator and operation is performed with a touch screen, the user can easily perform capture operations with the thumb of the hand holding the unit. Alternatively, operation control may also be provided using an electronic pen (not shown). In a development, the 127050 microphone / hearing aid has a 127060 switch device with which it can, for example, turn off the music playback and connect a phone call being received. At the end of the phone call, music playback can be turned on again by activating it again. The 127030 visual indicator and operation unit can be provided with its own processor or control device and its own rechargeable battery. For this reason, in that variant the program unit for playback can be executed directly on the 127030 unit of visual indicator and operation. As a result, it is possible in particular to resolve data formats protected against copying only in the visual indicator and operation unit 127030 and feed them to the hearing aid. The cryptographic encryption of the data flow between the mobile device 127010 and the visual indicator and operation unit 127030 can be performed, for example, by an SSL protocol. With that configuration, the element decoder (not illustrated) can be provided with the digital rights management system in the mobile 127010 device without the risk of unauthorized copying. In that execution, it is possible, for example, to send the content by continuous flow of the portable computer as a garment to a player or navigator installed for that purpose in the visual indicator unit and operation, while the preconditions for this are fulfilled, for example by a smart card of rights connected in the portable part as garment or the part of visual indicator and operation. ? A particular embodiment of the visual indicator unit and operation is the possibility of representing the operator control function of the unit of equipment to be controlled and the possibility of viewing, for example, multimedia content that has just been reproduced, along with the associated information such as title, amount of saved value, playing time, etc., or lists of multimedia elements that can be reproduced or ordered. With a multifunctional embodiment of the visual indicator unit and operation, for example, both as a media player and with the mobile phone function, it is possible to automatically switch between displaying, for example, telephone numbers and titles being played at a given time, or titles that are available or can be ordered, depending on the mode of operation or as a response to an entry. If a telephone call is made at any given time, the subscriber can be displayed or even represented by image, and if, for example, a piece of music is played (deleted during the telephone call), the corresponding information is displayed on the screen . The mobile device 127010 can interact, via a data LAN connection, with other devices such as an e-book reader, PDA, network tables, PC or video controller of the., Same or similar form, if appropriate arrangements are made For that purpose. The mobile device can also interact with the Internet via a different WAN connection than a wireless one via GSM, GPRS, ÜMTS, etc., the aforementioned connection being, for example, by analog telephone line, ISDN line or by DSL. Fig. 32B shows a side view of the mobile device 127010. For the convenience of carrying it nicely, when the mobile device is placed in a garment belt (not shown), the box has an ergonomic shape having a depression 127070 on the side of the belt. For convenience, rechargeable batteries (not shown) are conveniently arranged in the bottom of the case. An embodiment where the box can rotate relative to the belt by means of a connecting element (not shown) so that it can always be oriented approximately in a gravitational direction, is particularly advantageous. Ordinary peripherals, for example, printers, etc., can be connected to the mobile device 127010 in a developed embodiment. Fig. 33 shows the visual indicator unit 127040 and operation of Fig. 32. In a particularly preferred embodiment, the visual indicator and operation unit 127040 has, on the sides 128010a, 128010b of the upper and lower end, respectively, a clamped connection device (not shown) by means of which a lid module 128020 can be tightened and fitted onto the visual indicator and operation unit 127040 and possibly can also establish an electrical connection therewith. In a specific embodiment, the cover module 128020 is provided with a telephone keypad and has a window for displaying the visual indicator and operation unit 127040, and may have a hearing aid and microphone- (not shown), if the microphone it is not included in the 127040 unit of visual indicator and operation. The cover module 128020 can be realized in a wide and elegant range of shapes and colors. The purpose is: a) to allow the user to make telephone calls in the same manner as is customary with a conventional mobile telephone, and b) to allow a device originally configured as a playback device to be subsequently modified to form a mobile telephone, or vice versa. The cover module 128020 has the ability, in the connected embodiment, to be plugged in from above or below to the visual indicator and operation unit 127040 depending on whether the user has a preference for the left or right hand. What appears on the display of the 127040 unit of visual indicator and operation is automatically oriented accordingly so that texts and images can always be read. In a simplified embodiment, these features may also be omitted. Another advantageous embodiment of the visual indicator and operation unit 127040 is the lateral formation of capture elements or operator control oriented in the opposite direction to the screen, at the edge of the screen where the visual indicator unit 127040 and Operation can be sustained and operated at the same time by hand. A particular embodiment is to implement the capture unit by means of at least three keys of capture buttons allowing certain key functions, for example, sheet display, movement and activation of marked functions or menus. The position and number of plugs and connectable connections (if any) and the capture possibilities may vary in an individual case. The plug-in connection is particularly advantageous thanks to the possibility of connection to a convenient means, for example, in a vehicle (not shown), the operation control and the capture and emission of sounds can be done by the same interface as the module covering. The advantage of the separate 127040 unit of visual indicator and operation is in particular the compact design that can be made of very light weight. In mobile radio applications, the GSM or ÜMTS transmission antenna can be arranged at a distance from particularly sensitive body parts, such as the head, by mounting it on the mobile device 127010 which can possibly be positioned away from the body, for example on a table. The unit of visual indicator and operation and the portable part as a garment (computer) can also be made in one piece as long as the execution forms and / or manifested functions are implemented, for example, a DRM solution using an intelligent module and / or a PCMCIA module, a reception and / or transmission module for telephony, media player and PDA combination, remote control for terminals and / or a lid with window solution. Of course, the realization of a manual mobile device with a cover that can be opened and closed that has a window to see the screen below it, is feasible in a great variety of executive forms. The advantageous roof with an observation window serves as the basis for an independent inventive idea. The advantage of the observation advantage in the unfolding cover of mobile manual devices is in particular to allow a display that is presented to read even when the protective cover is closed, and other functions can be offered when closing the cover, without being required another screen for that purpose. As a result, the use of the cover therefore comprises all mobile manual devices with functions that are specified in the present manifestation, for example, PDA, telephony, (wireless and / or wired) and / or media players with or without remote control functions. It is also possible to realize the particular cover design of being permanently associated with a moving component of visual indicator and operation, regardless of whether the visual indicator component and operation is performed in one piece with a control unit or in more than one piece with an external portable computer as a garment. Fig. 34 shows the possibility of using the display unit and operator control of Fig. 32 for different equipment units and applications. The unit 127040 of visual indicator and operation unit can be always ready to be used on the person or close to the person and can collaborate with a number of other electronic devices within the distance that can be set aside to use, for example, Bluetooth or infrared (IrDA). For example, for the supervision of houses, game consoles, television sets, fixed line telephone, video controllers, video recorders, multimedia players, mobile phones or PDAs. Furthermore, Fig. 34 shows a fixed version 129010 which is similar to a mobile device with the same functional and technical realization possibilities, including those of DRM-protected content of continuous flow to the corresponding display components. The difference from the mobile device 127010 of Fig. 32 is that, for example, relatively large hard disk memory systems can be easily integrated. In addition, with the fixed 129010 version, the option of a fixed network connection and a satellite communication connection option is offered as the primary WAN connection, while in the case of the mobile device, GSM, ÜMTS or a fixed network is preferable. In the fixed 129010 variant it is possible to offer an external audio output, since it is advantageous to separate the image and the sound by means of a digital rights management system. The 127040 unit of visual indicator and operation, described in the foregoing, of. a mobile device can also be used to perform the operator control of a fixed station, which is an advantage for the user, since it can perform operator control and visualization functions, and have them on screen, in the customary manner in its usual display unit, without needing another remote control. Another advantage of the 127040 visual indicator and operation unit is that it is possible to perform both operator control of different devices, as shown, and receive audio channels without having to go via an external output of the fixed device, to which they are connected. external output speaker systems usually (remote control with headband). A wide variety of applications, for example for the supervision of houses, game consoles, television sets, fixed line telephone, video controllers, video recorders, multimedia players, mobile phones or PDAs, can also be performed at station 129010 Fixed.- The unit 127040 of visual indicator and operation advantageously detects if it is in the range of a terminal that has been registered to execute operator control. On the screen, a corresponding symbol is shown for the respective terminals that can be operated. In different transmission paths, for example a fixed network or a radio network for the transmission of signals between the visual indicator and operation unit 127040 and the respective terminal, it is also possible, in a particularly preferred embodiment, to select the respective transmission more economically. effective When used as a telephone, the visual indicator and operation unit 127040 uses a uniform record of addresses and telephone numbers and decides, depending on the telephone number and the subscriber participating in the call, which transmission route is selected as the most convenient or the best . All functions of the visual indicator unit and operation can be initiated by voice command control, regardless of whether the mentioned unit is made in one or two parts. Reference 129020 denotes the PCMCIA module which represents, in a form of execution, a digital rights management system (DRMS) with decoder function and which can be easily connected back and forth between the fixed station 129010 and the mobile device 127010 . In particular, functions 129030 can be supported by a DRMS. As in the case of the mobile device, the PCMCIA module can be provided with a smart card reader and / or an internal data memory to store, for example, licenses, DRM program units, programmatic player units, browser, information about rights, information about status, user privileges and / or consumer history to the extent that these are not implemented through physical technology or are actually planned. Of course, the full manifested content of the options described in the foregoing, particularly of the distribution and payment system, as well as their aspects, can be applied in various forms of execution for both the mobile and the fixed solution. Fig. 35 shows a preferred embodiment of the distribution and payment options described above, in the form of a PCMCIA card, with a smart card reader, which allows, when interacting with a reproduction device, the consumption of data protected multimedia, with a corresponding basis for the billing of said data, Fig. 47 shows a schematic block diagram for an additional inventive device for distribution, reproduction, billing and payment of digital media content. A digital media content provider (not shown) operates a server computer that connects via a digital network, for example via the Internet (not shown), to a media playback component 4720 that is located on the consumer side of the media. means (not shown). In the embodiment shown by way of example, the media player component 4720 is an audio player with at least one speaker or headband 4722 that obtains digital audio data from the 4710 server via a streaming protocol, and the It converts into sound that can be perceived by the consumer of the medium. Of course, the invention is not limited to audio media; it is equally possible also to distribute and consume video media, e-books or other media content in modified execution forms, a condition being that they have display means. • The reproduction function of the media reproduction component 4720 depends on control signals of a transaction control component 4730 that transmits a enable signal (not shown) to the media playback component 4720 only if content billing is ensured of media consumed in accordance with the charge scheme. For this purpose, the identification and verification of the authenticity of the consumer of the media is first required. An authentication identification and verification component 4740 is connected to the transaction control component 4730 and has a convenient user interface (not shown) by which the media consumer can identify and verify their authenticity. In a very simple variant, this can be done, for example, because the media consumer has to capture his user name and his personal password by means of a request on a screen (not shown). If the username and the user's personal key, which are stored securely in the authentication and authentication component 4740, it is assumed that the captured username matches and all of the following media consumption actions will be billed to that consumer of media that identifies in that way. In a more sophisticated variant of the authenticity identification and verification component 4740, it is also possible to use a physical element 4745, for example a smart card, to ensure authenticity identification and verification processes. Other means for verifying authenticity such as, for example, fingerprints, speech recognition and / or other known means of identifying and verifying biometric authenticity can also be provided. Additionally, the transaction control component 4730 is connected to a monetary transfer control component 4750. The currency transfer control component 4750 accepts, from the transaction control component 4730, instructions regarding money amounts for which the media consumer must receive invoices, and sends signals to the transaction control component 4730 if the billing These amounts of money have been completed, or if at least they can be considered as insured. The transaction control component 4730 controls the media reproduction component 4720 in a specific manner, with the effect that the media consumption is interrupted as soon as the monetary transfer control component 4750 stops indicating that the billing of quantities of money that the consumer of means must have been completed, or at least considered as insured. The monetary transfer control component 4750 is preferably connected to a first computer system 4760 of a financial institution where the media provider or the billing entity authorized by the provider has an account, as well as a second computer system 4765 from a financial institution, where the media consumer has an account. This connection can be made, in particular, via the customary billing data centers of the bank or the credit card company. If necessary, the monetary transfer control component initiates the transfer of a specific amount of money from the media consumer's account to the account of the media provider or the billing entity authorized by him. In order to avoid a rapid repetition of a large number of monetary transactions of very small amounts of money, which unnecessarily increases the cost of the monetary transfer, it is convenient to provide the consumer with a credit system, to request advance payments or to combine both and to provide a 4755 monetary account where a number corresponding to the amount due by the consumer of the means is stored, or the amount paid for the advance associated with the media consumer. The monetary transfer control component 4750 can then be preferentially configured such that the transfer order that is executed outwardly with respect to the computer systems 4760 and 4765 of the financial institute is only issued from time to time if an or exceeds a previously defined credit limit for the media consumer, or if an advance payment made by the media consumer has been used. Additionally, a component 4735 of bonus points memory, where at least one amount (number of bonus points) is saved corresponding to the accumulated financial value for the media consumer, but without expressing it as the amount of money of a national currency, it is connected to the 4730 transaction control system. The scheme of charges for media consumption actions that is carried out by the consumer of means and the generation of additional bonus points, based on those consumption actions, in component 4735 of bonus points memory is made in particular from in accordance with the principles and features specified in parts of the preceding description. An alternative embodiment is described in Figures 16 and 17. In order to make the use of the media as simple as possible for the media consumer, in a preferred embodiment, for example, provision is made for the provider of the means makes accessible a catalog server 4770 with a search component 4775 (search engine). By means of the catalog server 4770 with the search component 4475 (search engine), the media consumer can comfortably search the entire offer of the media provider, for example, with reference to data associated with the title, composer, type, album and / or artists. If the available information is less extensive, an alphabetical index may suffice; in the case of very large amounts of information it is advantageous to have a full text search. If the media consumer has found, through the catalog server 4770 and the search engine 4775, an item that is of interest to them, it can generate a data record for that item in a 4780 list of items by a convenient dialog in the operator interface (not shown). In addition to listening to or viewing samples, component 4720 can be activated only through list 4780 of elements; the media consumer can not consume an item for which there is no data record in the 4780 list of items. Conversely, the generation of a data record for a specific item in the item list 4780 does not necessarily mean that a consumption action has been performed causing charge. The 4780 list of elements rather constitutes a data structure that combines data from those elements that the media consumer considers potentially interesting. From the resulting list of the search component it is possible to reproduce elements for a previously determined time, for example. However, the 4780 list of elements not only serves as a memo memory only for specific information of elements such as author or title, but it also constitutes the basis for a specific administration of elements of element usage options by the media consumer. It is preferably possible in particular that the information be stored for each element in the list 4780 of elements, indicating: if any use of the respective element depends on the consumption, that is, it is invoiced as a function, for example, of time or volume, or the element is classified as "obtained free of charge" in accordance with the rules of the applicable charge scheme, that is, the item can be consumed in an unlimited way without further charges; "if a physical copy of the respective item has been purchased at a price reduced in accordance with the schedule of charges due to previous online use, corresponding information can also be represented in the list of results of the search component, in particular also information indicating whether items have already been registered, and if so, in which list of elements An operator control interface (not shown) assigned to the 4780 list of the particular elements also comprises measures for transmit an order through an item management component 4790, reduced in accordance with the bonus points stored in the bonus points memory component 4735, for the purchase of a physical item from a 4795 distributor system. Along with the purchase process, the amount of bonus point stored in the bonus point memory component 4735 is then reduced in accordance with the charging scheme, conversely, in a preferred embodiment, it is also possible to foresee that the consumer of means acquires, by means of purchase, a physical element, for example an audio CD, in a store. If at least one item stored on the audio CD can also be called online via the 4710 server, it is possible to arrange for the media consumer to have permission to write down, - in a corresponding item entry in the 4780 elements, which in accordance with the charge scheme may make use of that element online in the future free of charge or under preferential conditions, to the extent that this is not automatically carried out on the provider's side, for example when a product is purchased by a convenient method and / or technological provisions. Protection against misuse can be ensured by the distributor by feeding the 4795 distributor system the purchase action together with an identification of the item and together with the personal data of the consumer of the media, to the extent necessary to identify it unequivocally, so that the 4790 item management component can verify the purchase action. Another way to protect against misuse can be that each item purchased, that is, for example, each purchased audio CD is provided with an unambiguously defined code number. That code number can be implemented as a sufficiently large random number that is printed on an attached note and covered with a non-transparent cover layer. The random number has to have a number of digits that is so large that the probability of being able to guess it as a function of the edition is small enough for practical purposes. All random numbers that are issued respectively as a code number are stored in a database on the dealer's system. Additionally, for each issued code number there is a note indicating whether or not it has been used for a discount in accordance with the charge schedule. The media consumer can then remove the non-transparent cover layer and transmit the code number to the component management component 4790 via a convenient operator control interface (not shown). The element management component transfers that number. code to the dealer system 4795 where tests are performed to determine if it is a valid code number registered in the database and is marked as not used. In such a discount transaction, the code number is marked in the database as used and a corresponding discount is entered in the respective data record (or in the case of a multiplicity of items, a multiplicity of items is also entered). respective data records) in the 4780 list of elements. It is also possible to make the corresponding rights register by means of a solution of physical elements, for example, a smart card. A variation of the form of execution is foreseeing that the rights associated with an element (rights of use) are saved, together with an identification of the element defined in a univocal way, directly on the smart card. Here it is possible to access the data and modify it only by the supplier or the distributor system. The invention, therefore, provides the possibility of combining the online virtual use of digitizable elements and the acquisition of elements by purchase in the most advantageous manner. If the media consumer first begins the online use of a specific item, the proposed technical infrastructure enables the consumer to purchase a corresponding physical copy, when that media consumption is billed in accordance with a charging system, at a discount rate. . Conversely, if the media consumer first begins with the purchase of a physical copy, their access could possibly be allowed free of charge from the same item, in accordance with the charge scheme. If the technical arrangement described in the foregoing is operated in a way, where it is not foreseeing that individual elements are acquired, "free of charge", still a billing according to consumption according to the charging scheme continues to be possible. In that case, a simple authenticity check with a personal key may suffice as regards the component 4740 for identifying and verifying authenticity, as the media consumer will then develop, based on the cost consequences associated with each consumer action, a high degree of motivation to protect your access data and in particular not to disclose them to third parties. The situation is different as soon as it is allowed to "acquire" items free of charge. By limiting the cost consequences, there is a risk that individual media consumers freely disclose their access data to third parties. In such circumstances, the physical element 4745, which is difficult to simulate, proves to be very advantageous for purposes of verifying authenticity. Fig. 48 shows a schematic view of a development of the arrangement shown in Fig. 47. While only one catalog server 4770 and one content server 4710 of an individual content provider were provided and therefore always requires an online connection to a content 4710 server, the development shown in Fig. 49 includes a memory component 4712 that is equipped with a medium (not shown) of memory of sufficient digital volume and to which content data of digital elements downloaded from one of the content servers 4710 can be saved. , so that they can also be consumed offline by the media consumer, that is, without having an online data network link open. Off-line local availability of an element in component memory * 4712 is recorded in the corresponding data record of element list 4780 that is associated with the respective element. The different inventive charge scheme modes described in the foregoing also apply to offline consumption of items that are stored in component memory component 4712. As financial transactions can not be executed via financial institutions 4760, 4765 during off-line consumption, in this variant the 4755 monetary account is not only a convenience, but a necessary one. In all arrangements shown in Figs. 47, 48 and 49, a DR S (not shown) with an implementation component (not shown) is preferably used in order to protect the digital data content against misuse. The arrangements shown in Fig. 47, 48 and 49 can be implemented technically in a variety of ways. In particular, computer programs running on universal computers can also be represented. While the servers 4770, 4710, 4760, 4765 and 4795 are generally run as computers installed and operated out of reach. of the media consumer, the other components, with the exception of the physical element 4795, can be incorporated, for example, by means of a package of programs running on a PC. However, it is also possible to use specific devices for particular applications that implement these components in another way, for example by means of suitable electronic circuits. Fig. 50 shows a schematic overview of a phase model for the commercialization of multimedia products for purchase based on the arrangements shown in Fig. 47 to 49. Three phases are distinguished: a) Phase 1: an arrangement in accordance with Fig. 47 is typically applied in phase 1, with three operator control steps available on a specific basis per provider, that is, with no functions covering more than one provider; b) Phase 2: An arrangement in accordance with Fig. 48 is typically applied in phase 2, where elements that are "free of charge" purchased from different content providers can be combined, managed and reproduced based on more than one provider. c) Phase 3: An arrangement in accordance with Fig. 49 is typically applied in phase 3 where elements from various content providers can be downloaded based on more than one provider to a mass memory medium of a consumer's multimedia application. media, be managed and reproduced either online or offline. Fig. 51A shows a schematic view of an operator control interface as an example of a first aspect of a first subordinate step in accordance with the first phase of the phase model of Fig. 50. A menu bar 5110 is displayed in a display device (not shown in greater detail). The menu bar 5110 allows the activation of a search function, divided into categories of music elements, videos, games and electronic books. A bar 5112 of alphabetical index allows the search by alphabetic index by the name of the artist leafing through the alphabetical index. A corresponding alphabetical index search is also possible by other criteria such as the title of an element, the album, the genre, etc. (not shown in detail). As a result of the search process, a list 5115 of results appears in which all the elements contained in the result set are related in tabular form with one row each. In the case of the example of the "music" column, a consecutive enumeration is given, the title of the element, the name of the artist and the name of the album. Additionally, a first operator control element 5115a is generated by each element, wherein the actuation of that first operational control element 5115a, for example by operating a mouse, causes the respective title to appear briefly for a predetermined time depending on the element , for example, for 30 seconds. Additionally, a second operator control element 5115b is generated for each element, being that by actuating said second operator control element 5115b, for example by operating a mouse, an element that has been searched for subsequent transfer to the "" is marked. "playlist", that is, to the 4780 list of elements of Fig. 47. A direct transfer of individual elements is also possible if an operator control element (not shown) is installed for that purpose. Fig. 51B shows a schematic view of an operator control interface by way of example, of a second aspect of the first slave step in accordance with the first phase of the phase model of Fig. 50. The consumer of means (not shown) has caused an appropriate data record to be generated from the list 4780 of elements in the result list 5115 by driving the second operator control element 5115b for a number of items marked 5117a, 5117b, 5117c, 5117d and the consumer receives a 5120 display of online playlist in the operator control interface. In a preferred embodiment, the display 5120 of the online playlist can be configured so that it can be sorted and / or grouped according to user defined categories or genres 5122a, 5122b, 5122c, 5122d, 5122e. Fig. 51C shows a schematic view of an operator control interface by way of example of a second subordinate step of the first phase of the phase model of Fig. 50. It is possible, for example, by operating a mouse, selecting and reproducing an individual element or a complete playlist with a multiplicity of 37 elements of the online playlist 5120 display. The media reproduction component 4720 of Fig. 47 then appears in the operator control interface in the form of an 5130"online player" object with the usual functions such as start / stop, fast forward, fast return. The reproduction function of object 5130"online player" is enabled only if the transaction control described in relation to Fig. 47, 48 and 49, allows the transfer of money in accordance with the regulation. When the reproduction function of object 5130"online player" is activated by the corresponding operator control element, consumption-oriented billing of usage charges is initiated, or as shown in Fig. 51C, the conversion of official means of payments to amounts of monetary value specific to the content provider, and the aforementioned amounts can be used advantageously only for the purchase of products and / or services of the respective content provider. Fig. 51D shows a schematic view of an operator control interface as an example of a first aspect of a third subordinate step of the first phase of the phase model of Fig. 50. The 4790 administration of elements of Fig. 47 appears in the operator control interface in the form of a "product manager" object with a product list 5142 where physical copies of items that can be purchased, here CD albums by way of example, are related and preferably shown by icons, where it is particularly advantageous to configure the icons in accordance with the front page of the CD booklet to ensure a good recognition effect. When you click on an icon in the list 5142 of products, the respective icon is displayed in the field 5144 of the product. Elements 5146a, 5146b, 5146c associated with the field 5144 of product are generated in order to be able to drive, several commercial transactions relating to the CD album that is symbolized with the icon in the field 5144 of products. By actuating the first element 4146a,, operator control causes the amount of bonus points stored in the bonus point memory component 4735 of Fig. 47 to be reduced by 400, and as a result all elements of the album are acquired free. 'charge for online use, which is also marked in the list of items. Acting the second element of operator control element 4146b has the effect, in the case of usage rights that had already been previously acquired (see above), of reducing the number of bonus points stored in memory component 4735 bonus point of Fig. 47 by 800, and as a result a contractual promise is triggered by the content provider or an authorized intermediary to provide a physical copy of the respective album to the respective media consumer under the control of component 4790 elements and the 4795 distributor system. Acting the third operator control element 4146c causes the saved value of the media consumer that is represented in the monetary account 4755 to be reduced by 15 Euros, and an order is triggered by a physical copy of the respective CD album of a content provider or an intermediary agent that is authorized by the aforementioned provider, without the prior condition of having previously acquired and use rights. For this purpose, the order is advantageously carried out by means of a basket of goods (not shown). Of course, other products or services of the supplier can also be purchased using purchased points. ? Fig. 51E shows a schematic view of an operator control interface as an example of a second aspect of the third subordinate step of the first phase of the phase model of Fig. 50. After having acquired usage rights for all elements of the respective CD album by actuating the first operator control element 5146a, a data record is displayed in the display of online reproductions list 5120 of the media consumer ("Hans Mustermann") for each of the elements contained in the CD album, with the data record indicating that the rights of use have been acquired, that is, that the item is "acquired free of charge". A list of reproductions with all the titles in the album is advantageously generated automatically. Titles that are already in lists of individual items are also marked and if they are included in the album that has already been purchased free of charge they can be reproduced free of charge. Of course, relationships explained in the foregoing with reference to the CD album can easily be transferred to other digitizable elements such as, for example, videos or electronic books. A distribution on demand of digital content, for example, via a data network such as the Internet or via a terrestrial transmission channel or via a cable channel or satellite channel turns out to be very broadband intensive, particularly if relatively small quantities are requested of different elements by a very large number of individual users at different times. There is, therefore, in practice a very large need to propose a device that saves broadband capacity, or a corresponding method that saves broadband capacity. In the inventive solution of this object it is possible to use a channel, for example a terrestrial transmission channel, preferably during a first time interval, for example, from 09:00 a.m. local time at 24:00 p.m. local time for the continuous sequential issuance of samples of cryptographically non-encrypted extracts of digital elements, called a trailer. The trailer can be related in particular to video films, audio media or games. By means of an inventive device, for example in the form of what is called video controller, it is possible for the media consumer to see, during the day, the sequence of trailer emissions and finally arrive at a decision, after a process of consideration , to see specific elements, for example, video films, associated with the individual trailers that have been seen, in the full version the next day, for example. With the inventive method, the media consumer then indicates, during the exposure time of the corresponding trailer, that he wishes to 'consume the corresponding full version by activating an operator control means which can be arranged, for example, in the video controller in a remote control associated with the video controller. For this purpose, a remote control (not shown) equipped with a screen is advantageous, as presented in the foregoing as a universal remote control in Fig. 32 to 34. It is possible to display corresponding identifications of the element on the screen, such as, for example, , titles, and trigger, through a direct key, a function that performs a configuration in the video control. This can be a filter configuration that makes it possible to detect and download an element that will be transmitted later by broadcasting. Other elements that have not been marked in the video control are not enabled for download. Another possibility is to previously set a time period configuration, transmitted toer with the trailer, for example, which makes it possible to receive a specific program at a specific time in a predetermined channel, since the program is transmitted in a non-tard manner by means of a broadcasting mode. It is optionally possible for the device, for example in the form of the video control, to send a consumption request via a convenient return channel, for example via a telephone line or via the Internet, * to a server of the content provider. During a second period of time, for example from 01:00 a.m. local time at 08:00 a.m. local time, the content provider's server distributes the digital content requested by individual consumers, by the same channel that has been used to distribute the trailers during the first period of time. The video controller is then configured with a - medium, mass memory (for example a hard disk with a capacity of 160 Gbytes) and. a control unit so that it is possible during that second period of time to separate from the set of all digital elements transmitted in encrypted form cryptographically in broadcasting mode, those elements whose trailer has been marked by the media consumer during the first period of time, and of storing the mentioned element in cryptographically encrypted form on the hard disk. During this automatic process of unloading and storage, no operator control intervention of any kind is required by the media consumer. At the latest after the second period of time has ended, all digital elements ordered by the media consumer have been stored on the hard disk and can be consumed by the consumer after deciphering. It is advantageous to protect the content data by a DMRS and to identify and verify the authenticity of the authorized media consumer before allowing access to the 'content data; the latter being preferably carried out again by means of a physical element, for example, by means of a smart card. Fig. 53? shows a schematic view of a device and a method for broadcasting digital content in a first step of the method. On a 5210 channel, product presentations with a trailer are continuously transmitted in broadcast mode during a first period of time from 09:00 a.m. at 12:00 a.m. Between the trailers it is possible, if it turns out to be necessary, to also place advertising blocks. In an even more improved variant it is possible to provide the consumer with means with monetary advantages, for example in the form of bonus points, to consume these advertising blocks. A variant that is even more improved, is defined by the fact that a specific symbol, for example a number or a pattern of letters is included in each block of advertising (advertising). The media consumer then receives bonus points in the latter improvement only if during the capture or for a short period of time afterwards he captures the symbol recognized by him, for example by means of a keyboard provided on the remote control of the video control, and of this way it verifies that it has really consumed the advertising block. Channel 5310 is evaluated by video control 5320 according to the invention. The individual trailers and the associated full versions can be identified by suitable measures, for example, by means of identifiers of unique elements or by the precise specification of the period of time during the transmission of the corresponding full version. The consumer (not shown) marks the trailer A in the example shown by operating an operator control means on the operator control part 5330 (eg, a remote control) of the video control 5320. The trailer can be consumed, for example, by a 5340 screen and / or a 5350 speaker. Fig. 53B shows a schematic view of a device and a method for broadcasting digital content in a second step of the method. On channel 5210, the full version corresponding to the trailer is transmitted in encrypted form cryptographically in broadcast mode during the second time period of 01:00 a.m. at 08:00 a.m. and they are selected under the control of the control unit 5360 and stored in the memory module 5370. ., Fig. 53C shows a schematic view of a device and a method for broadcasting digital content in a third step of the method. By means of a physical element (smart card), the consumer of means is identified and verifies its authenticity with respect to the compensation chamber from which the specific cryptographic decryption key for the decoder is obtained for the digital content stored in the memory module 5370 . Fig. 53D shows a schematic view of a device and a method for broadcasting digital content in a fourth method step. The digital content, for example a video movie associated with the trailer A which is stored in the memory module 5370, can be decrypted cryptographically and consumed under the control of the control unit 5360.
